which two pairs of points lie on perpendicular lines?
a. (-6,-,18)
b. (6,,12)
c. (-4,,3)

this is my second time asking this question : (

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Factor the expression using the gcf. the expression 21m−49n factored using the gcf

What is the total area of the figure?
