Answer:


m = (6)/(4) = 1 (2)/(4) = 1 (1)/(2) = 1.5

Explanation:

Use rise over run. (
(rise)/(run))

Your rise value is how much the y has gone up (or down) from one point to the next.
y_(1) =3
y_(2) = 9. You can figure out what your rise is by using the equation
y_(2) -y_(1) = rise. So, our rise is 6.

Now, solve for your run value. Your run value is how much the x has gone up (or down) from one point to the next.
x_(1) =1
x_(2) = 5. You can figure out what your run is by using the equation
x_(2) -x_(1) = run. So, our run is 4.

Now that we have our rise and run values, insert them into the fraction
(rise)/(run), and simplify.
(rise = 6)/(run = 4) = (6)/(4) = 1 (2)/(4) = 1 (1)/(2) = 1.5

Hope this helps. Have a great day!

Answer:

3/2

Explanation:

Slope is change in y over change in x (y2-y1 over x2-x1)

The change in y would be (9) - (3), which is 6.

The change in x would be (5) - (1), which is 4.

6/4 is also 3/2, which is the slope.
