Question

Write the equation of the line that is perpendicular to y= -1/4x+2 in slope-intercept form and passes through the point (-4,3)

Answer 1

I believe that the perpendicular equation would be the opposite sign and the reciprocal of the original slope. Then you just plug in the x and y coordinate to y=mx+b and solve for b.
y=4x+b
3=4(-4)+b
3=-16+b
b=19
y=4x+19

Answer 2

This would probably be better answered in mathematics. Anyways your answer is y=4x+19. Hope I helped you.
