Point-slope form:
y - y1 = m(x - x1)

plug in the given
slope = 2
point (-1,7)

y - 7 = 2(x - -1)
y - 7 = 2(x + 1)
y - 7 = 2x + 2
add 7 to both sides
y = 2x + 9

Hope this helps!

Answer:

The point-slope form of the line is y - 7 = 2(x + 1)

Step-by-step explanation:

In order to find the equation of the line, you start with the base form of point-slope form.

y - y1 = m(x - x1)

Now, input the slope in for m and the point in for (x1, y1).

y - 7 = 2(x + 1)
