Question

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

Answer 1

for x, put a point on 0,8

for y, put a point on -2,0

it should look like this

Answer 2

The y intercept occurs when x = 0:-

y-intercept is -1/2(0) - 4 = -4 answer

x0intercept is found by putting y = 0:-

0 = -1/2 x - 4
1/2 x = -4
x = -8 answer

To draw the graph plot the points (-8,0) and (0,-4) and draw a straight line through these points.
