Double first equation: 10x + 2y = 10Subtract second equation: 7x = 7x = 1, y = 0
It is a straight line equation that needs to be rearranged into slope-intercept form as folows:- 7x+2y = 5 Subtract 7x from both sides: 2y = -7x+5 Divide all terms by 2: y = -3.5x+2.5 which is now in slop-intercept form
the answer to this problem is -2x^2y^2
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
7x is still the slope, no matter what x equals.
