2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
x=1
2x+4 = -16 2x = -16-4 2x = -20 x = -10
10
It is an equation and the value of x works out as 88
2x+y = 10 or y = -2x + 10 so the slope is -2
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
-5y +2x = -10 -5y = -2x -10 y = 2/5x +2 So the slope = 2/5 and the y intercept = 2
y = -2x+10
2x - 5y = -10 So 5y = 2x + 10 and therefore y = (2/5)*x plus something So the slope is 2/5 or 0.4
Slope = 2
Slope is 2.
2
2x + y = 20 y = -2x + 20 Slope = -2 m=-2
The slope is -2x and the y intercept is 5 Note that it will be a negative slope.
Slope-Intercept Form: y = -2x +1
y=-2x+9
