Jacob charges $10 per hour to babysit and $60 to clean the house. Write the expression which represents Jacob's earning for cleaning one house and babysitting?

60 + 10h

Step-by-step explanation:

Since cleaning the house is a flat fixed cost ($60 no matter how long it takes), you dont use a variable to find it. For baby sitting on the other hand, the cost of it is reliant on how long you do it ($10 for every hours). Therefore you need to use a variable (h).

I hope this helps!

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
