Answer 1

Answer:

its D

Step-by-step explanation:

Answer 2

Answer:

y = 2x + 75

when x = 0, y = 75

when x = 11, y = 97

when x = 20.25, y = 115.5

when x = 58, y = 191

Step-by-step explanation:

To get the total number of pages she has read, y, after x minutes have elapsed. We will have to go by general form of equation which says  

y = mx + b where m is the rate of change or simply the slope, which is 2 pages/minute. and y-intercept will be the number pages she has already read. Our equation will now be y = 2x + 75

The next step is to start substituting the numbers in to the equation

When X = 0  

y = 2(0) + 75 = 75

when x = 11

y = 2(11) + 75 = 97

when x = 20.25

y = 2(20.25) + 75 = 115.5

when x = 58

y = 2(58) + 75 = 191

when x = 0, y = 75

when x = 11, y = 97

when x = 20.25, y = 115.5

when x = 58, y = 191
