Answer:
Option c is correct.
Equation with slope of 7 is; 
Step-by-step explanation:
The Equation of line is in the form of :
.....[1]
where
m represents the slope of the line.
x represents the variable.
Given : The slope of a line is 7
m = 7
substitute the value of m =7 in [1];

Therefore, the equation of line which graphs to a line with a slope of 7 is, y =7x
Answer:
2x+4
Step-by-step explanation:
mx+b
goes up two then over one, best way to remember is ryse over run ! rise with a y meaning y goes on top, so technically the answer would be

the plus four is the 'b' or the y intercept so where the line crosses the vertical y.
hope this helped !
Answer:
B
{(8,-9), (-8,-5), (8-7), (-8,-6)}
Step-by-step explanation:
A function can have two X values but not two Y values
I think you want to convert it all to feet.
1 mile = 5,280 feet
2 miles = 5,280 × 2
5,280 × 2 = 10,560 feet
10,560 + 500 = 11,060 feet
2 miles and 500 feet is equal to 11,060 feet
