To get your answer, you will need to find the perpendicular slope for -1/3x which is just the opposite therefore it will be 3x. Your slope is 3x as perpendicular so use this slope to do point slope. Y-1=3(x-2). Distribute y-1=3x-6. Add 1 to both sides. (-1+1) (-6+1)=-5. So your equation in slope intercept form is y=3x-5. Going through the two points.
Hope this helps!
Answer:
196 miles
Step-by-step explanation:
if he goes 140 miles with 5 gallons, each gallon lets him go 28 miles.
140miles/5gallons=28miles/1gallon
then 7 gallons lets you go 196 miles
brainliest please :)
