Slope formula = y2 - y1/ x2 - x1
SF = 3 - (-3)/ 2 - 5
SF = 6/ -3
Slope = -2
Now we need to find b (the y-intercept)
y = mx + b
y = -2x + b
3 = -2(2) + b
3 = -4 + b
+4 +4
7 = b
The equation of the line should be:
y = -2x + 7
From the information we have, Jack drove 401/2 miles and used a total of 1 1/4 gallons of gasoline.
We need to find out how many miles he travelled per each gallon.
40 1/2 miles can be written as 40.5 miles
1 1/4 gallons can be written as 1.25 gallons.
So now we form an equation.
40.5 = 1.25
x = 1
Where x is the number of miles per gallon
We cross multiply the equation
40.5 * 1 = 1.25 * x
40.5 = 1.25x
40.5 / 1.25 = x
32.4 = x
x = 32 .4
So the unit rate for miles per gallons is 32.4 miles per gallon
1 YEAR = 12 months
divide: 5,031 ÷ 12 = 419.25
419 dollars and 25 cents each month

1 is the closest to 0 on the number line. Hope this helps!!!!!!!!
Answer:
-27
Step-by-step explanation:
Number be x
Eight added to number: x+8
sum is doubled: 2*(x + 8)
-11 less than number: x -11
2*(x + 8) = x -11
2*x + 2*8 = x - 11
2x + 16 = x - 11
2x - x = -11 -16
x = -27
