Hey there!
We are given 2 points that the line passes through, so we can easily determine the slope of the line:
So now we have the slope.
However, we also need to find the y-intercept (we are actually given the y-intercept, (0,7) or just 7)
Hence, the equation is
Hope everything is clear.
Let me know if you have any questions; if you do, please comment.
