Line ab goes through the points a (0,-4) and b (6,2). which equation represents line ab?

y = x - 4

Step-by-step explanation:

Base on point A we have X = 0 and Y = -4

then we have this equation:

Y = ax + b

<=>-4 = a*0 + b

<=>-4 = b

so equations have the form of Y = ax - 4

Base on point B we have X = 6 and Y = 2

Y = ax - 4

<=>2 = a* 6 - 4

<=>a * 6 = 6

<=>a = 1

so equations have the form of Y = 1x - 4 = x - 4

so the equations represents line AB is Y=x - 4

Done :))

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

false

inverse variation is not exponential
