Slope for the equation y equals 7 is zero.
2xy=2*30*2=120
The slope is 4.4 and the y intercept is -7

If: y = 7 then there is no slope and the line will be parallel to the x axis
Slope for the equation y equals 7 is zero.
2xy=2*30*2=120
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
The slope is 4.4 and the y intercept is -7

2xy substitute 3 for y and 5 for x 2(5)(3) = 30
If: y = 7 then there is no slope and the line will be parallel to the x axis
4x+y = 7 y = -4x+7 in slope-intercept form So the slope is -4
15xy-2xy-7x+x=13xy-6x
Slope = -1
x2 + y2 = x2 - 2xy + y2 + 2xy = (x - y)2 + 2xy = 72 + 2*8 = 49 + 16 = 65 You could, instead, solve the two equations for x and y and substitute, but the above method is simpler.
