So first write the equation in slope intercept form y=mx+b
5x-2y=7
5x=2y+7
5x-7=2y
5/2x-7/2=y or y=5/2x-7/2
now that you know the slope(5/2x) of the equation all you do change the slope to the negative reciprocal which is -2/5x-------> the answer you're looking for

Solve this system of equations using any method. 2x – y = 5 4x + y =7
Natalija [7]
Substitute on equation 2, y = -4x + 7. so equation 1 becomes 2x - (-4x + 7) = 6x - 7 = 5. 6x = 12, so x = 2. from above, y = -4x+7 = -4(2) + 7 = -1
