Let's say we had y isĮqual to negative seven, what's the slope and y-intercept there? Well, once again, you might say, hey, this doesn't look This as five x plus zero, and then it might jump out at you that our y-intercept is zero and our slope is aĬoefficient on the x term. I only have one term on the right-hand side What's the slope and y-intercept there? At first, you might say, hey, this looks nothing Let's say that we had theĮquation y is equal to five x. Here, what's the coefficient? Well, you can view negative x as the same thing as negative one x. But what's my slope? Well, the slope is theĬoefficient on the x term but all you see is a negative Might immediately recognize, okay, my constant term, when it's in this form, that's my b, that is my y-intercept. So, we could rewrite this as y is equal to negative x plus 12, negative x plus 12. Term before the constant term, so we might wanna do that over here. The standard form, slope intercept form, we're used to seeing the x Similar is going on here that we had over here. You can determine the slope and the y-intercept. Let's say that we have the equation y is equal to 12 minus x. And then it becomes a little bit clear that our slope is three, theĬoefficient on the x term, and our y-intercept is five, y-intercept. It doesn't matter which one comes first, you're just adding the two, so you can rewrite it as y isĮqual to three x plus five. So, if you wanna write it in the same form as we have up there, you can just swap theįive and the three x. Here, it's not five x, it's just five, and this isn't three, it's three x. Taken you a second or two to realize how this earlier equation is different than the one I just wrote. Y-intercept in this situation? Well, it might have Let's say if we hadįorm y is equal to five plus three x, what is the slope and the So, that's pretty straightforward but let's see a few slightly And b is just going to be thisĬonstant term, plus three. So, if we just look at this, m is going to be the coefficient Is equal to the slope, which people use the letter m for, the slope times x plus the y-intercept, which people use the letter b for. In slope intercept form where it has a form y Y-intercept in this example here? Well, we've already talked about that we can have something Let's say we have something of the form y is equal to five x plus three. So, let's start with something that we might already recognize. Substitute slope and y-intercept form to the general equation of slope intercept form to calculate it.Like to do in this video is a few more examples recognizing the slope and If you need to calculate the slope using two points, use slope calculator. Step 2:Write the slope form equation and place the values. To find equation of a straight line with slope and y-intercept, follow the example below.įind the Straight line equation if y-intercept is 6 and slope is 4. Y = mx + c How to find the slope intercept form (equation of a straight line)? In UK, variable c is used to represent y-intercept. The equation of slope intercept varies in USA and UK. x, y represents the x and y coordinates,.The slope intercept equation can be represented as: Slope intercept is a form of linear equation that can be used to find the equation of a straight line with y intercept and slope of line. Slope intercept form calculator is an online tool that is used to find slope intercept form (equation of line) using two points, y-intercept, or one point and slope.
