Answer:
a. The x and the y values are flipped, it reads left 2 down 4
b. it should be (x+4, y+2)
Step-by-step explanation:
when it is plus on x it is left and when it is negative on y it is down

Answer:
y= -3.5x +10
Step-by-step explanation:
The first thing to do in this equation is solve for m, the slope of the line.
Because we are given that the y-intercept is 10, we know that the graph intercepts at the point (0,10).
We are also given the point (5,-7.5).
Using the two points we can solve for the slope!
To solve for the slope use this formula: ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
(-7.5 -10) / (5 -0)
= -3.5
So our slope, m = -3.5
The other missing value is b, but is very easy to find.
In this example, b is equal to the y-intercept, so b=10.
Now we can plug in the values we found into the original equation
y =mx+b
y= -3.5x +10
