Given:
Points ( -2, 2 )
x1 = -2
y1 = 2
m = 2
Formula for the point-slope form:
y -y1 = m (x - x1)
Formula for the slope-intercept form
y = mx + b
Solution:
Solve for point-slope form first, before going to slope-intercept form.
Substitute the given values of x1, m and y1 to the formula for the point-slope form.
y - 2 = 2 ( x - (-2))
y - 2 = 2 (x + 2)
In order to equate to slope-intercept form, we simply need to distribute 2 to each value inside the parenthesis, and then transpose -2 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
y - 2 = 2x + 4
y = 2x + 4 - 2
y = 2x + 2
Final answer:
y = 2x + 2
