Question

Determine the slope and the y-intercept of the graph of the equation.

y = -4



a. m = -4; (0, 0)
b. m = 0; (0, -4)
c. m = 1; (0, -4)
d. m = 0; no y-intercept

Answer 1

The graph of y = -4 describes a graph where no matter what value of x you choose, you get a value of -4 for y. This means that the graph is going to look like a horizontal line that sits on y = -4. Since it is flat, the slope is zero, and obviously it will intersect the y axis at (0, -4)
