5x + 2y = -10 general line equation form is: y= mx + c so 2y = -10 - 5x y = -2.5x - 5 m refers to gradient and c is offset on the y axis so gradient is -2.5 (gradient means slope)

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.

5 times ten is fifty JHC
3y = -5x+2 y = -5/3x+2/3 The gradient is -5/3 and the y intercept is 2/3
5x + 2y = -10 general line equation form is: y= mx + c so 2y = -10 - 5x y = -2.5x - 5 m refers to gradient and c is offset on the y axis so gradient is -2.5 (gradient means slope)

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.
y5x-1y5x=1y=1/5xTherefore the gradient is 1/5x
5 times ten is fifty JHC
