Answer:
Step-by-step explanation:
Use the "point-slope" formula for the equation of a straight line,
y - k = m(x - h)
Here the slope, m, is 3 and the line passes through (h, k): (-4, -7), so the proper equation in this case is
y - (-7) = 3(x + 4), or:
y + 7 = 3(x + 4).
If you wish you may rewrite this equation in slope-intercept form, as follows:
y = 3x - 7 + 12, or y = 3x + 5
