Use elimination and subtitution method to solve the problem. First, eliminate x and you'll find the value of y x - 4y = 12 x - y = 0 --------------- - (substract) -3y = 12 y = 12/-3 y = -4
Second, subtitute -4 as y and you'll find the value of x x - y = 0 x- (-4) = 0 x + 4 = 0 x = -4
A parallel line would have the same slope as the given line so first you'd rewrite the equation y-x=5 to y=x+5 the slope is the x value so the slope is 1.
The answer would be D. If it was a causation it would be B. But a correlation would be something like a secreted sap in the berries. A correlation is a mutual connection in two things. Mark Brainliest if this helps as I am trying to rank up! Thanks!
