Question

The equation for a line that has a y-intercept of -8 and passes through (-4,2) is y=-5/2x-8 True False

Answer 1

1) Let's verify whether that's true or not, plugging in that point into the equa

(-4,2)

$\begin{gathered} 2=\frac{-5}{2}(-4)\text{ -8} \\ 2=10-8 \\ 2=2 \end{gathered}$

Since this is an identity, in other words, the left side is equal to the right side then we can say that's true.

So that's true y=-5/2x-8 is the equation of the line that has in one of its points the y-coordinate y=-8
