The cost of renting ice skates at a skating rink is $1.25. The rink charges $3.25 for each hour, x, of skating. Which graph best
posledela

Answer:

A

Step-by-step explanation:

Since the total cost at first will not be 5 exactly, it will turn to 4.5 (4.50). And it will be just below the five, at the first hour. And then from there, just add 3.25 each hour and forget about the 1.25 since 1.25 is used for the beginning only, and not the rest.

Find the slope of a line that passes through (-2,1) and (4,9)
melamori03 [73]

Answer:

m = 4/3

Step-by-step explanation:

To find the slope of a line use the formula, where "m" means slope:

m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }

*You don't need to show this part on paper*

Choose which point you want to be point 1 and point 2. Remember the points are written (x, y).

Point 1: (-2, 1)       x₁ = -2  y₁ = 1

Point 2: (4, 9)      x₂ = 4   y₂ = 9

Substitute the coordinates into the formula:

*Show this part on paper*

m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }

m=\frac{9-1 }{4-(-2) }         Simplify

m=\frac{8 }{6 }                Reduce by dividing by 2

m=\frac{4 }{3 }               Slope

The slope of the line is 4/3
