Answer:

Step-by-step explanation:
To write an equation, use the slope-intercept equation:

M is the slope and b is the y-intercept.
First, find the slope by using the slope formula for when you have two points:

Rise over run is the change in the y-axis over the change in the x-axis. Substitute values:

Simplify parentheses (two negatives make a positive) and simplify:

The slope, m, is 4. Insert this information into the equation:

Now, take one of the points and insert into the slope-intercept formula:

Solve for b, the y-intercept. Simplify multiplication:

Add 20 to both sides and simplify:

The y-intercept, b, is 20. Insert this value into the equation:

Done.
Answer: 0.2
Step-by-step explanation:
subtract 9.38 - 3.5 = 5.88
distribute the 1.2.
7.56 - 8.4x = 5.88
subtract 5.88 - 7.56 = -1.68
-8.4x = -1.68
divide both sides by -8.4
answer = 0.2
