Question

Please Help Me! The question is :

Without graphing find the slope of the line that passes through the points (2,2) and (4,6).
Use the change in y over the change in x.

Answer 1

y = 2x - 2

Explanation:

y2 - y1 / x2 - x1

6 - 2 / 4 - 2

4 / 2

=2

y = 2x + b

2 = 2(2) + b

2 = 4 + b

-2 = b

Answer 2

Answer:

Solution given:

`(x_1,y_1)=(2,2)`

`(x_2,y_2)=(4,6)`

now

slope:
`(y_2-y_1)/(x_2-x_1)=(6-2)/(4-2)=(4)/(2)`=2

Slope: 2
