Question

The graphed line can be expressed by which equation?

A. Y+2=2/3(x+2)
B. Y-2=3/4(x-1)
C. Y-1=-3/4(x-2)
D. Y-2=3/4(x-2)

Answer 1

Answer:y+2 = 2/3(x+2)

Explanation:

You can’t find this answer by taking the two points on the line and setting them up as x-x and y-y and finding the slope And then using the slope to find the equation of the line.

Answer 2

y+2 = 2/3(x+2)

Explanation:

We have 2 points (-2,-2) and (4,2)

so we can find the slope

m= (y2-y1)/(x2-x1)

= (2--2)/(4--2)

= (2+2) / (4+2)

= 4/6

= 2/3

The slope is 2/3

We can use point slope form to find the equation of the line

y-y1 = m(x-x1)

y--2 = m(x--2)

y+2 = 2/3(x+2)
