Answer: y= -1x - 5
Step-by-step explanation:
The equation has to be in slope-intercept form which uses the formula
y=mx+b where m is the slope and b is the y-intercept.
So we given the slope and an x and y coordinate so we will plot those numbers into the formula and solve for the y intercept to write the equation.
the x coordinate is -7 and the y coordinate is 2
2 = -1(-7) + b
2 = 7 + b
-7 -7
b = -5 the y intercept is -5
Now the equation will be y= -1x - 5
21-8=13 so hope that helps x
Answer:
$70.56
Step-by-step explanation:
Lets convert the mixed number (trip length) to decimal.
We know 3/5 (by long division) is 0.6, so 705 3/5th = 705.60 miles
Now, let's come to the problem:
1 gallon = 28.8 miles (mileage)
or
$2.96 = 28.8 miles
To find cost per mile, we divide:

That means, it costs $0.10 per mile
Since we want to travel 705.60 miles, we multiply to find the cost:
$0.10 per mile * 705.60 miles = $70.56
Im sorry i have no clue what this is
