Question

Choose the graph below that correctly represents the equation 15x - 5y = 30.


How would I graph this?

Answer 1

let's find the x and y intercepts and draw a line through those two points...

Answer 2

set x=0, solve for y to get the y-intercept.
set y=0, solve for x to get the x-intercept.

Answer 3

0,6 and 0,0?

Answer 4

or 0,6 and 0,2

Answer 5

set x=0 so 15(0) - 5y = 30 ---> -5y = 30 ---> y=-6 so (0, -6)
set y=0 so 15x - 5(0) = 30 ---> 15x = 30 ---> x=2 so (2, 0)

Answer 6

the first one (0, -6) is your y-intercept
the second one (2, 0) is your x-intercept

Answer 7

now just plot those two points and draw a line through them...:)

Thank you(:
