Answer:
y= (5/4)x I'm pretty sure

Step-by-step explanation:
The line will have the same slope as the given line, which is m = 3. Therefore, the equation of the line in its slope-intercept form is

Next we need to solve for b by plugging in the coordinates of the given point:

So the equation of the line is

Answer:
r = 7
Step-by-step explanation:
Use the distributive property by multipling the -8 to the 2r and the -8, do the same thing on the other side with the -3.
Afterwards, combine like terms by adding 64 and 6.
Next, add 3r to the left side, I usually choose the number with the variable (the letter) that looks like it will be easier to subtract. This leaves only 21 on the right side.
Next subtract 70 from both sides
Divide -13 by both sides
You should get the answer of r=7
Explanation:
First you had to square from both sides of equation form.

Then you expanded form.



Solve by equation form.

Add by four from both sides of equation form.

Simplify.

Verified solutions.
