Question

Given the equation y − 3 = (x + 6) in point-slope form, identify the equation of the same line in slope-intercept form.

x − 2y = −12

y = x

y = x + 6

y = x + 9

Answer 1

slope intercept form is y = mx + b

y - 3 = x + 6 (add 3 to both sides)
y - 3 + 3 = x + 6 + 3 (combine like terms)
y = x + 6 + 3
y = x + 9 < -- slope intercept form
