Question

Which equation represents the line that passes through (0,8)and(2,0)

A.y=4x+8
B.y=-4x+2
C.y=-4x+8

Answer 1

The answer is C.

y= -4x + 8
You can plug in your coordinates.


For (0,8), plug in the x and y values.
8 = -4(0) +8
8 = 0+8
8=8 so, this works

For (2,0) plug in your coordinates.
y = -4x + 8
0 = -4(2) + 8
0 = -8 + 8
0=0

If both coordinates work for the equation, then they pass through that line.
