Well what you want is y = mx + b
m = slope
b = intercept for y
with that just substitute in the slope and the intercept, but leave the x and y as it is. So later on you can put in a x coordinate and get the y coordinate through that, hope this helps!
Answer:
Step-by-step explanation:
Answer:
6 times a larger number (so 6y) is equal (=) to the sum of a smaller number and 18 (x+18)
6y = x+18
Twice of larger number (2y) and the difference of smaller number (x) is equal to 6
2y - x = 6
solve for y. Divide both terms for 6.
6y/6 = 1/6x+3
y = 1/6x+3
second equation solve for y
move x to the right of equal
2y = x + 6
y = 1/2x + 3

Answer:
4 chocolates
Step-by-step explanation:
Before Luke started eating, there were 8. This is 2/3 of what Sara had to start with, so she started with 12. That is 3/4 of what Mike started with, so he started with 16.
Jill left 4/5 of what she started with, so she must have started with 20. Jake ate 1/6 and left 5/6, so 20 is 5 times the number Jake ate.
Jake ate 4 chocolates.
___
Jill ate 4; Mike ate 4; Sara ate 4; and Luke ate 4.
