<span>Use formula: (a-b)</span>² = a² - 2ab + b²<span>
(r-1)</span>² = r² - 2r + 1
3(7t+5)= 36
First, distribute into parentheses
21t+15= 36
Subtract 15 from both sides
21t= 21
Now divide both sides by 21
t= 1

Answer

Explanation
A linear equation can be written in the following form:

where <em>m </em>is the slope and <em>b </em>the <em>y-intercept</em>.
As we are already given the slope, then we get the equation:

Replacing the point given we can calculate b:


Then the equation is:

Then, we would have to get the form Ax+By=C , however, as we do not want fractions, we have to multiply the equation times two:

Rearranging the function we get:
