Question

What is the equation of the following line? Be sure to scroll down first to see

all answer options.

Answer 1

B

Explanation:

The slope intercept form for a line is y=mx+b, where m is the slope and b is the y intercept. Since this line rises 9 units for every 1 it moves to the right, it has a slope of 9. Since it goes through the origin, it also has a y intercept of 0. Therefore, the equation of this line is y=9x, or answer choice B. Hope this helps!

Answer 2

y= 9x

Explanation:

y=mx + c

m=slope

m= 9-0/1-0

m=9

using point (0,0)

0= 9(0)+ c

c=0

Therefore y = 9x
