Given the equation:
y - 8 = 2(x + 4)
Rewrite the equation in slope-intercept form.
Solution:
In order to write the equation in slope-intercept form, we start first by distributing 2 to each value inside the parenthesis, and then transposing -8 to the opposite side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
y - 8 = 2(x + 4)
y - 8 = 2x + 8
y = 2x + 8 + 8
y = 2x + 16
Final answer:
y = 2x + 16
