Answer:
The equation of this line is y = -3x + 29
Step-by-step explanation:
In order to find this, start with the basic form of point-slope form.
y - y1 = m(x - x1)
Now put the slope in for m and the point in for (x1, y1)
y - 8 = -3(x - 7)
Now solve the equation for y.
y - 8 = -3x + 21
y = -3x + 29
