Answer:
y=1/5x
Step-by-step explanation:
Slope is 1/5. The y-intercept is 0.
Yes, 6/8 reduces to 3/4 by dividing the numerator and denominator by 2.
Do 40x10=400. Then do 40x6=240. Lastly, add 400+240=640.

Answer:
y = 2/7x - 1
Step-by-step explanation:
You are trying to put it in the form y = mx + b where m is the slope and b is the y-intercept.
To start, find the slope by doing change in y (between the two points) divided by change in x (between the two points). This would be:
3 - (-3) (change in y) / 14 - (-7) (change in x)
= 6/21
= 2/7
So the slope is 2/7.
Then, you have the equation y = 2/7x + b.
Since you know the point (14, 3) works, you know x = 14 and y = 3 is a solution to the equation. You can plug in those values which would be:
3 = 2/7 * 14 + b
3 = 4 + b
-1 = b
So that means the equation is y = 2/7x - 1
