If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.

y = 5x + 9
5x - y + 1 = 0
5x-y equals 18 = -13
If y equals 5x-15 and x equals 1 then the value of y comes out to be -10. So y equals 5x-15 is -10.
Yes.
5x=11y
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.

y = 2x -1 y = 5x -13 So: 5x -13 = 2x -1 5x -2x = 13 -1 3x = 12 x = 4 and by substituting y = 7

5x + y = 5

The origin.
y = 5x + 9
