Question

Which of the following is not a step used when graphing the equation x - 2y = 4 using the
x- and y- intercepts method ?
Choose one answer.
a. Plot the y-intercept (0, -2).
b. Plot the intercept (4, 0).
c. Count up 1 and right 2 from the y-intercept.
d. Draw a line through the two points.

Answer 1

This is x and y intercept method:

Make x=0 to find y-intercept.
x - 2y = 4
0 - 2y = 4
-2y = 4
/-2
y = -2
(0, -2)

Make y=0 to find x-intercept
x - 2y = 4
x - 2(0) = 4
x - 0 = 4
x = 4
(4, 0)

And then cross a line through the two points.

C is the answer. Why? You only do that step when you change the equation to slope-incercept and solve.
