Ldentify an equation in point-slope form for the line perpendicular to
1 answer:
9514 1404 393
Answer:
D
Step-by-step explanation:
The given line's equation is in slope-intercept form:
y = mx + b
where m = -4 is the slope, and b = -1 is the y-intercept.
The slope of the perpendicular line will be ...
-1/m = -1/(-4) = 1/4
You want the point-slope equation for the line, which is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
Your equation will have m=1/4, (h, k) = (-2, 7), so it will be ...
y -7 = 1/4(x +2)
