Determine the slope of the line connecting (3, 10) and (7,22)

3

Step-by-step explanation:

The slope of the line connecting two points is the change in y over the change in x. The change in y between these points is 22-10=12. The change in x is 7-3=4. Therefore the slope is 12/4 or 3.

b) 36

step-by-step explanation:

18 times 2 is 36

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
