Answer:
Step-by-step explanation:
The slope formula is M=y2-y1
______
X2-X1
Ex. (-1,1) and (1,-2)
x1,y1 x2,y2
-2+1 -3
_____= ____
1+(+1) 2
Graph:
Any linear function can be quickly graphed using the form: y=mx+b
X: independent variable
y: dependent variable
M: slope
b: y-intercept
(When you don't have a denominator for M put a 1 Ex. 4--> 4/1)
Ex. y=-1/2x + 4
M= 1/2
B: 4
Rise/Run = -1/2 "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).
