Explanation:
Since we have given that
Speed at which Eugene walked all the way to school = 3 mph
After realizing that she forgot her math book, she ran back
Speed at which Eugene walked back to her house = 7 mph
Let the distance between her house and her school be x
According to question,

Hence,

Multiply 850 by 3 because it is 1/3 of her whole budget.
Answer:
y=x+1
Step-by-step explanation:
To find the line of the equation, use the slope formula to find the slope.
Slope formula is: y2-y1/x2-x1
9-3/6-2= 3/4
Once you have the slope, use that and one of the coordinates to put the equation in point-slope form.
Point-slope form is: y-y1=m(x-x1), with m representing slope and y1 and x1 representing the x and y coordinates.
y-3=1(x-2)
With the equation in point-slope form, you can now distribute 1 to x-2 and simplify to put it in slope-intercept form.
y-3=1x-2
y=x+1
