Question

Write an equation in slope-intercept form for the line described. Slope 9/2, passes through (0,-13/2)

Answer 1

Use slope-intercept equation form: $y=mx+b$

We know that the slope is 9/2

$y=\frac{9}{2}$

$y=\frac{9}{2}x+b$

To solve for b, we can plug in the point given, since it's on the line.

$-\frac{13}{2}=\frac{9}{2}(0)+b$

$b=-\frac{13}{2}$

So the equation is: $y=\frac{9}{2}-\frac{13}{2}$
