Answer:
A, E
Explanation:
Solving for y, the coefficient of x tells us the slope of the given line.
y = (-x +50)/5
y = (-1/5)x +10 . . . . . the given line; has a slope of -1/5
The perpendicular line will have a slope that is the opposite reciprocal of this value:
m = -1/(-1/5) = +5
That is, you want equations for lines that have a slope of +5.
__
As above, the slope is the x-coefficient when the equation is in y = ( ) form. This fact lets us identify A as one good choice, and reject B–D as incorrect choices.
When we divide the equation of E by 5 to put it into the desired form, we have ...
y = 5x +2.6 . . . has a slope of 5
The equations of interest are ...
- A. y = 5x +2
- E. 5y = 25x +13
