Question

Type the equation of the given line in standard form.

The line with m = 4 and the point (0, -9).

Thanks. Y'all (:

Answer 1

2 ways to do this

First way is use point-slope form: y - y1 = m(x-x1)
where (x1,y1) is given point
plug in the numbers
--> y-(-9) = 4(x-0)
--> y+9 = 4x
get y by itself
--> y = 4x -9

The 2nd way is use slope-intercept form: y=mx+b
plug in the point for x and y, then solve for b
--> -9 = 4(0) +b
--> -9 = b
therefore
--> y = 4x -9

Answer 2

Oh, okay. Thanks!
