Total distance John drove=450 miles
total time=8 hours
let the number of hours he drove on highway be x, number of hours he drove on turnpike will be (8-x) hours
since
distance=speed*time
distance traveled in highway=50x
distance traveled in turnpike=60(8-x)
thus the total distance will be:
50x+60(8-x)=450
simplifying the above
50x+480-60x=450
-10x=450-480
-10x=-30
thus
x=3 hours
Thus he drove on highway for 3 hours.
To convert an equation to slope intercept form, you have to isolate the y variable.
-2x + 3y = 15
Add 2x to both sides.
3y = 2x + 15
Divide all terms by 3.
<h3>y = 1.5x + 5 is the original equation in slope-intercept form.</h3>
I hope this answers your question!
