Answer:
y = 1/4x -10
Step-by-step explanation:
The equation would be y = 1/4x -10
we know that we have to set the equation up as y=mx+b
m being slope and b being y-intercept
we can see on the graph that the line intercepts the y-axis at -10, so that would be b
for slope, you can just look and count rise over run so:
it goes 10 up and 40 over which equals 10/40 also known as 1/4
hope that helped :)
We'll solve this equation in order to find the score of the 4th test, which we denote with x.
. Solving it we find that x=63. And it is the final answer for this problem.
10(1/2x + 5) = 7
That's the way to write the description of that equation. Good luck!!
