SOLUTION: graph f(x) = -2x + 2

Question 34611: graph f(x) = -2x + 2
Answer by lyra(94) (Show Source): You can put this solution on YOUR website!
Well, we can convert this to the form of a linear equation:
y=-2x+2
-2=-2x-y
2x+y=2

Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .

X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 2/2 = 1.
Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 2/1 = 2.
Slope is -2/1 = -2.
Equation in slope-intercept form: y=-2*x+2.

Hope this helps,
