Question

Plot the x- and y-intercepts to graph the equation. y=-1/2x-3

Answer 1

Answer:

Step-by-step explanation:

Given y=-1/2x-3, rewrite this as y = (-1/2)x - 3 for greater clarity.

x-intercept:  Let y = 0 and find x:  0 = (-1/2)x - 3, or

(1/2)x = 3, or x = 6.  Thus, (6, 0) is the x-intercept.

y-intercept:  Let x = 0 and find y.  Then (-1/2)(0) - 3 = y.  Thus, y = -3, and the y-intercept is (0, -3).

Plot these two intercepts and then draw a line connecting them.

Example:  To graph the y-intercept, start with your pencil point at the origin.  Move your pencil point 3 units down and plot a dark dot there.
