Question

B. Write the equation in slope intercept form. (y=mx + b). Remember, m is the slope, b is the y intercept (where x=0).

C. Make a scatter plot. Make sure to label.

Answer 1

y=5x+10

Explanation:

Use two points from the table: (1, 15) and (2, 20) to find m (m=
`(y_2-y_1)/(x_2-x_1)`)

m=
`(20-15)/(2-1)`

m=5

Use another point from the table as x and y: (25, 3) in the equation y=mx+b (we just found m=5). Solve for b

y=mx+b

25=5(3)+b

10=b

Therefore, knowing m and b the equation in slope intercept form is:

y=5x+10
