Question

If (k, 4) is a point
on the graph of the equation 4x + 2y=4, what is the
value of k?

Answer 1

k = -1

Explanation:

First we turn the equation into y = mx+b format then we we can plug in the value y= 4 and get 4 = -2x + 2

subtract two from both sides so 2= -2x divide btoh sides by 2 and get x = -1
