Line general formula is y = m*x + b. In this exercise, you knew a point which lies on the line and its slope. So, replacing in the formula and solving for b gives
7 = 3/4*3 + b
b = 7 - 9/4
b = 19/4
Then, the equation of the line is y = 3/4*x + 19/4
(b)
Replacing the point into the formula obtained previously and solving for x gives
<span>Assuming that this is referring to the same list of options that was posted before with this question, the correct response was the first one, although I forget what it was. </span>
