Write an equation of a line that passes through (7,1) and is parallel to y= -x + 3. y=mx+b

For a line to be parallel to another line they must have the same slope.  The slope of y=-x+3 is -1.  The slope for the other line must be -1 as well.  The equation for the new line that passes through (7,1) would be y=-x+8

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
