Find the slope of the line through (8, –9) and (–3, –6).

Slope = -3/11

Step-by-step explanation: I don't use the slope formula to find the slope. All I did was this:

8,-9

-3,-6

-

11, -3

8- (-3) = 11

-9 - (-6) = -3

-3/11 can't be simplified therefore, -3/11 (negative 3 over 11) is the slope.

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
