Question

Liam is reading a 254-page book for school. He can read 40 pages in one hour. The equation for the number of pages he has left to read is y=254-40x, where x is the number of hours he reads.

a. State the slope and the y-intercept of the graph of the equation.

b. Graph the equation.

c. Interpret what the slope and the y-intercept represent.

Answer 1

A.slope is 40x and y intercept is 254
B.look for 254 first on number line then do rise over run to find your line connect the dots
C.it represent the constant rate that he is reading

Answer 2

Answer:

THe y intersect is 240.

The slope would be -40

Step-by-step explanation:

In order to solve this problem you just hve to remember that the y form of the function is: 7=mx+b

m is the slope of the function, and the m is -40

Then the intersect with the y axis is calculated by setting in the function a value for x as 0, when x is 0, Y is 240. In the formula of the function the intersect is equal to B and M is equal to the number by which x is being multiplied.
