The slope of any line is the inclination of the line with x axis.
For any two ordered pairs (x1,y1) and (x2,y2) the slope
m=
We need to solve for y2.
Multiplying both sides by x2-x1 we have :
y2-y1=m(x2-x1)
y1 is subtracted to y2 so we perform the opposite operation both sides
Adding y1 both sides:
y2= x(2-x1)+y1.
The third option is the right answer.
Answer:
4x9=36
Step-by-step explanation:
36
Answer:
2
Step-by-step explanation:
So we want to know when the cost of each is the same:
2.5m=7.5+m subtract m from both sides
1.5m=7.5 divide both sides by 1.5
m=5
So renting 5 movies costs the same from either store. ($12.50)
