20.4 is the answer because there is 12 cm so you would multiply 12 by 1.7.
Point sloe is
y-y1=m(x-x1)
slope=m
a ponint is (x1,y1)
slope=(y2-y1)/(x2-x1)
(x,y)
(5,-3)
(-2,9)
slope=(9-(-3))/(-2-5)=12/-7=-12/7
m=-12/7
a point is (5,-3)
x1=5
y=-3
y-(-3)=-12/7(x-5)
y+3=-12/7(x-5)
2nd one
7/y....the coefficient of y is 1
any time u have a variable by itself, whether it is x or y or any letter, the coefficient is gonna be 1
Answer:
m = 
Step-by-step explanation:
I'm assuming by m, you mean the slope.
You have two points. (-11, 5) and (2, -4)
- m = change in y-value ÷ change in x-value
1) Substitute in the points.
m = 
2) Solve.
So, the slope would equal

22 dollars + 39 dollars = 61 dollars
100-61= 39 dollars. She needs $39 more
