Question 1157036

If a line passes through the points (1,3) and (-2,-9), the equation of the line is y - 3 = 4(x - ___).
<pre>It's clear from the given point-slope equation of the line, y - 3 = 4(x - ), that the coordinate point, (1, 3) was used. 
Therefore, it's {{{highlight_green(matrix(1,3, y - 3, "=", 4(x - 1)))}}}
