Find the slope of the line that contains the points (11,-17) and (7,1)

Step-by-step explanation:

Slope(gradient)=Y2-Y1/X2-X1

(11,-17) (7,1)

X1,Y1 and X2,Y2

m(slope)= 1-(-17)/7-11

m=18/-4

m=-4.5

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
