Answer:
y = 2x - 16
Step-by-step explanation:
perpendicular lines = have negative-reciprocal slope
slope: -1/2 => negative-reciprocal => 2 ↓ slope
substitute (4, -8) and the slope 2 into the slope-intercept form(y = mx + b) to find b:
=> -8 = 2(4) + b => b = -16
plug in the slope 2 and b = -16 to the slope-intercept form:
y = 2x - 16
