Question

What is the equation of the line in slope-intercept form that passes through the point (–2, 4) and is perpendicular to the line y = –2x + 4?
Answer

y = negative one-halfx – 5

y = negative one-halfx – 2

y = one-halfx + 5

y = one-halfx + 2

Answer 1

y = one-halfx + 5

(–2, 4) and is perpendicular to the line y = –2x + 4?
perpendicular slope m = 1/2
y - 4 = (1/2 ) ( x + 2)
y = x/2 + 1 + 4 = x/2 + 5
