Can someone please explain this to me? I don’t know what to do 1. Lines m and n are perpendicular. If the slope of line m is zero, then what is the slope of line n? If you were to sketch
lines m and n, what type of lines would you sketch?
2. On a graph, create your own set of perpendicular lines similar to lines m and n. Choose two points on each line and
prove through the slope formula, that the lines are perpendicular to each other.

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

i think this is a open ended question but i agree with other guy who said you should ask it at english section

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
