Question

Determine the x- and y-intercepts of the graph of y=− 1 2 x−4 . Then plot the intercepts to graph the equation.

Answer 1

Answer:

X intercept- ((-1/3),0)

Y intercept- (0,-4)

The x intercept is found when y is 0.

The y intercept is found when x is 0.

So we have to substitute 0 for the x and y variables in 2 separate equations.

y=-12x-4

y=-12(0)-4

y=-4

y=-12x-4

0=-12x-4

4=-12x

-1/3=x

The new Y intercept is (0,-4) and the new X intercept is (8,0).
