Question 609254
Hi, there--
.
The point-slope equation looks like this:
{{{y-y[1]=m(x-x[1])}}}
.
This this case m is the slope, 7/2, while x[1] and y[1] are the x- and y-coordinates of your point (-3,4). 
.
All we have to do is plug these values into the formula.
.
{{{y-4=(7/2)(x-(-3))}}}
.
Simplify to clear the parentheses around -3.
{{{y-4=(7/2)(x+3)}}}
.
Hope this helps! Feel free to email if you still have questions.
