Slope Intercept Form
Example of Distributive Property
2(3-4x) = 2 times 3 minus 2 times 4x or 6-8x
Standard Form
Ax+By=C
Slope Intercept Form
Slope intercept form consists of the x-intercept, the y-intercept, and the slope.
Finding slope given a graph
You could do y2-y1 over x2-x1
Direct Variation
y varies directly as x for y=kx, where k does not equal 0
Point Slope Form
y-y1=m(x-x1)
Slope Formula
y=mx+b
Finding y-intercept given an equation
y=mx+b. b represents y-intercept, so whatever took b's place is the y-intercept.
Finding slope given an equation
y=mx+b. m represents slope, so whatever took m's place is the slope.
Finding x-intercept given an equation
y=mx+b. replace y with 0 and solve for x.
