How do you change an equation into Y-intercept form?
How do you change an equation into Y-intercept form?
To change the equation into slope-intercept form, we write it in the form y=mx+b . We want to isolate the y, so our first step is to multiply both sides by 9. Then cancel out the 9’s on the right side.
How do you find the Y-intercept equation?
Using the “slope-intercept” form of the line’s equation (y = mx + b), you solve for b (which is the y-intercept you’re looking for). Substitute the known slope for m, and substitute the known point’s coordinates for x and y, respectively, in the slope-intercept equation. That will let you find b.

How do you convert a quadratic equation from standard form to intercept form?
To convert a function, from standard form f(x) = ax² + bx + c, to intercept form, we use the general intercept form expression (3). f(x) = a*(x + b/2a + d/2a)(x + b/2a – d/2a), with d² = b² – 4ac.
How do you find the y-intercept in standard form?
Using the standard form of an equation we can easily find the intercepts.
- To find the x-intercept, we set y=0 and solve for x.
- To find the y-intercept, we set x=0 and solve for y.

How do you find the y-intercept in intercept form?
When the equation is written in the slope-intercept form (y=mx+b) we can find the y-intercept by looking at the equation. The value of b is the y-intercept. This is because the y-intercept is when the x value equals 0. When x = 0, mx = 0, so when x = 0, y = b.
How do you convert standard form to intercept form?
How do you find the X and y intercept in standard form?
Writing an equation in standard form makes it easier to find the x and y-intercepts, which is where the graph crosses the x- and y-axis. All you have to do is plug in a 0 for the y to find the x-intercept or a 0 for the x to find the y-intercept.
What is the formula to convert standard to slope intercept form?
Converting Linear Equations (A) Convert standard to slope-intercept forms. 1.Standard form: 10x 7y = 8. Slope-intercept form: 2.Standard form: 8x+y = 9.
How do you find the y-intercept of a slope?
All you have to do is plug in a 0 for the y to find the x-intercept or a 0 for the x to find the y-intercept. In point-slope form, x1 and y1 are coordinates of a point on a graphed line, and m is the line’s slope. The slope-intercept form has the slope, m, and the y-intercept, b, on the right-hand side of the equation.
Why do we remove the coefficient(2) from the slope intercept equation?
In order to eliminate the coefficient (2) on Y. If the coefficient were left attached to that Y right there, then we would not have a value for Y by itself, which is what the slope-intercept equation requires. I hope that’s helpful!
