1. Define y-intercept of a line? 2. In the slope intercept form: y=mx+b, what do the variables x, y, m, b stand for?
3. Define Slope of a line. Define Rise and Run. What are the four types of slope?

Do the steps below on the graphing calculator:

Graph the points (2,6) and (6,8).

Define the equation y = mx + b.

Define the variable m = 1.

Define the variable b = 10.

What happens if you increase the value of m from 1 to 2?

✔ The line gets steeper.

Find the values of m and b that cause the graph to pass through the two points plotted.

m = ✔ 0.5

b = ✔ 5

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
