Answer:
slope 2.500
x intercept 1.80000
m intercept 4.50000
Step-by-step explanation:
<u>step 1:</u>
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
5*(x+4)-(-2*(-4-m)+3)=0
<u>step</u><u> </u><u>2</u><u>:</u>
-4 - m = -1 • (m + 4)
(5•(x+4))-((0--2•(m+4))+3) = 0
<em>step</em><em> </em><em>3</em><em>:</em>
5 • (x + 4) - (2m + 11) = 0
<u>step</u><u> </u><u>4</u><u>:</u>
5x - 2m + 9 = 0
<u>step</u><u> </u><u>5</u><u>:</u>
Solve 5x-2m+9 = 0
Sector area = (central angle / 360) * PI * radius^2
sector area = (210 / 360) * PI * 2.3^2
sector area = (7 / 12) * PI * 5.29

She should chose the $9 because it is cheaper ;)
