Question

Find the slope and y intercept of the line that is perpendicular to y= - 1/3x + 5 and passes through the point (-3,-7)

Answer 1

Answer:

Given equation of line is y = -1/3 x + 5

slope of this line is -1/3

so slope of line perpendicular to above line is 3

Also given perpendicular line passes through point (-3,-7).

so y intercept is -7+9 = 2
