Assuming you want the equation in slope intercept form, you first need to use slope formula to find the slope.
Plug in the coordinates that you have, (3,-1) and (4,7), for the x and y values respectively.
Which reduces to 8/1=8.
The slope of your equation is 8.
Slope intercept form is: y=mx+b. m is your slope and b is your y-intercept, x and y stay unchanged.
Plug the slope in:
y=8x+b.
Now, you can plug one of the sets of coordinates into the x and y of the equation to find b. I'm using (3,-1).
-1=8(3)+b
-1=24+b
Subtract 24 from both sides.
-25=b
Now plug this into the equation!
y=8x-25 is your final equation.
I hope this helps :)
Answer:
(-1/2, 1)
Step-by-step explanation:
it's just coordinate planed
Y = -2x + 8 <=== this would be ur equation where x is the number of hrs and y is the total distance (in miles) from home

Answer:
Yes, they are correct. Hernando divided 6 by 6.
Step-by-step explanation:
Given that:
Hernando ate 2/8 of a pizza for dinner.
Let the pizza be x. Then:
Hernando ate 
Then he gave the rest of the pizza to his friends
Hernando now carried out the following calculations to support his activities;
From the above calculation; we will see that Hernando divided 6 by 6 in both cases to get 
.
Thus, the correct answer is:
Yes, they are correct. Hernando divided 6 by 6.
