Question

Write the equation of the line in slope-intercept

form that passes through the given points.
(2, 0) and (4,1)

A) y=1/2x-1
B) y=-3/4x+7
C) y=6x+1
D) y=3x+5

Answer 1

Answer is A the slope is 1/2


1-0=1
4-2=2 1/2

To check we fill in y and x with coordinates (2,0) and (4,1)



y=1/2x-1. 0=1/2(2)-1. 1=1/2(4)-1
0=1-1. 1=2-1
0=0. 1=1
Meaning that after checking the answer is correct.
