Question

He equation of the graphed line is 2x – y = –6.

Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?

y = 2x – 2
y = 2x + 2
y = x + 2
y = x – 2

Answer 1

y=X+2

Explanation:

you can use the equation y=Mx+c to give this solution!

Answer 2

Explanation:

Find the slope using the points

`Slope =(y_(2)-y_(1))/(x_(2)-x_(1))\\\\\\=(6-2)/(4-0)\\\\\\=(4)/(4)\\\\\\=1`

m= 1.

y = mx + c

y = 1*x+ c

y = x + c

In this equation substitute x = 0 and y = 2 and find the valu of c

2 = 0 + c

c = 2

Equation of line CD:

y = x + 2
