What is the answer to questions 4-6?

Step-by-step explanation:

Slope intercept form of a line passing through points is given by where b is the y-intercept i.e, point at which the line intersects the y-axis , m represents the slope given by

4.

b = 1

Equation is  y=2x+1

5.

b = - 5

m = 0 as the line is parallel to x - axis

Equation is y = - 5

6.

b = 4

Equation is

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
