At teresa's auto shop, it takes her
15
minutes to do an oil change and
18
minutes to do a tire change. let
x
be the number of oil changes she does. let
y
be the number of tire changes she does.
using the values and variables given, write an inequality describing how many oil changes and tire changes teresa can do in less than
2
hours (
120
minutes).

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

b. x + 1

step-by-step explanation:

i'am smart

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
