Question

Please help me

A line passes through the origin, (3,5), and (-12, b) what is the value of b?
A) -20
B) -7
C) -10
D) 20​

Answer 1

A) -20

Explanation:

AS it passes through the origin (0,0) and the point (3,5) we can find the slope
(y2-y1) / (x2-x1) =
(5 -0 ) / (3-0) =

5/3

Becasue is passes through the origin the equation is :
5/3x = y

For the other point (-12,b) -12 is "x" and "b" represent "y" in the equation

-12 * 5/3 = -60/3 = -20

b = -20

The Answer A) -20 is the one
