For two complementary angles find x. The first angle is 4x+9. The second angle is 2x+27

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
