I think the parent function is
y=x
<span>If Charles leaves the marina and sails his boat 10° west of north for 1.5h at 18km/h, then makes a right turn towards 60° east of north for 1.2h at 20km/h, he is 42 km from his starting point.</span>
No solution because if you distribute -4 to both 2.5y and -3.25 your equation becomes -10y+13-15 1/4=-10y. Then you subtract both 13 and 15 1/4 and get -2.25 so your equation becomes -10y-2.25=-10y. After that you add 10y to both side so your equation becomes -2.25=0 which has no solution.

Find the slope of the line that passes through the pair of points.

In this problem we have two points given to us, which are...
... and we should find the slope.






Answer:
Use the equation mx+b=y
mx represents the slope and b represents the y intercept.
So, this would mean the equation is : 1/2x + -7 = y
