There is a proportional relationship between minutes and cost in dollars. the graph passes through the point (1, 4.75). what is the slope of the graph? what is the unit rate? explain.

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

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

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

the correct answers i think are b. and d.

give me brainliest if it is correct!
