It's 2. your equation is y=mx+b, so the gradient, or slope, is the "m" in the equation.
Gradient = 2
Gradient = 2
Gradient = -2 y-intercept = -4
They are both parallel because the slope or gradient is the same but the y intercept is different.
-6
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
it equals 13X.
2
-2
-1 divided by the gradient (2) = -0.5 so y= 0.5x
x=1
Gradient to the curve at any point is the derivative of y = x2 So the gradient is d/dx of x2 = 2x. When x = 2, 2x = 4 so the gradient of the tangent at x = 2 is 4.
