Question

Choose the correct procedure used to graph the equation 15x - 5y = 30 using the intercepts method.

Answer 1

you have to put it in your own words. here are the choices:
A: Solve the equation for y to get a y-intercept of (0, -6) and a slope of 3. Plot the y-intercept, count the slope to get another point and draw the line that passes through the two points.

B: Choose two different values; plug them into the equation to find the corresponding y-values. Plot the two points and draw the line that passes through the two points.

C:Solve the equation for y to find an intercept of (-6, 0); solve the equation for x to find a y-intercept of (0, -2). Plot the two points and draw a line passing through the two points.

D:Let x equal zero and solve for y to find a y-intercept of (0, -6). Let y equal zero and solve for x to find an x-intercept of (2, 0). Plot the two points and draw a line passing through the two points.

Answer 2

first solve for the x-intercept (i.e. set y=0):
15x - 5(0) = 30
15x = 30
x = 2
the point is therefore (2, 0)

then the y-intercept (set x=0):
15(0) - 5y = 30
-5y = 30
y = -6
the point is therefore (0, -6)

this is effectively the same method as D.
