Given the line in point slope form:
y + 1 = 3(x - 2)
Let's rewrite the equation in slope intercept form.
Using the point slope form:
y - y1 = m(x - x1)
Thus, we have the following:
x1 = -2
y1 = 1
slope, m = 3
To write in slope intercept form, all you have to do is to isolate the y.
Thus,
y + 1 = 3(x - 2)
Expand the parenthesis:
y + 1 = 3x - 6
Subtract 1 from both sides:
y + 1 - 1 = 3x - 6 - 1
y = 3x - 6 - 1
y = 3x - 7
Therefore, the equation in slope intercept form is:
y = 3x - 7
ANSWER:
y = 3x - 7
