The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

substitute the coordinates of the points (8, 0) and (20, 12) to the formula:

y = 1x + b = x + b
Put the coordinates of the point (8, 0) to the equation of a line:
0 = 8 + b <em>subtract 8 from both sides</em>
-8 = b
<h3>Answer: y = x - 8</h3>
Answer:
you multiple the y-intercept and then multiply the x-intercept and then find the slope.
Step-by-step explanation:
Answer:
5a + 5b
Step-by-step explanation:
a(5 + b) = 5a + 5b
you just multiply a to 5 and a to b.
2. Because if 1/3 + 2/3 is 1 then 1+1=2
Answer:
3x - 20 = 13
Step-by-step explanation:
1. The word is signals the equal sign.
The difference of three times a number and 20 = 13
2. The word difference signals subtraction.
3. The phrase a number sigals that the number is unknown, so a variable should be used. In this case, I'll use x.
4. Three times that number = 3x.
The difference = subtraction.
3x-20=13
