Question

Choose the correct procedure used to graph the equation 3x - 4y = 12 using the intercepts method.
Choose one answer. A. Solve the equation for y to find an intercept of (-3, 0); solve the equation for x to find a y-intercept of (0, 4). Plot the two points and draw a line passing through the two points.
B. Solve the equation for y to get a y-intercept of (0, -3) and a slope of . Plot the y-intercept, count the slope to get another point and draw the line that passes through the two points.
C. Choose two different values; plug them into the equation to find the corresponding y-val

Answer 1

The easiest first step would be to put the equation into slope intercept form, y=mx+b and then examine the possible answers. You know that if you set x=0 you will get the y intercept, let logic lead you from there. :)

Answer 2

so itd be c?

Answer 3

Choosing different values might give you points along the line but you only get an intercept when one of the values is 0. Any point on the 'y' axis has an 'x' value of 0, similarly any point on the 'x' axis has a 'y' value of 0.

Answer 4

what does that even mean?? @eSpeX

Answer 5

@jen1511 If you are referencing the last comment, it means that the intercepts (which is the method they want used) are where either the 'x' or 'y' value in the pair is zero, therefore 'c' is the answer if and only if the two points you plug in are zero for x and then zero for y.
Despite the points being wrong, I would have chosen 'a' as a solution here.
