Answer:
Step-by-step explanation:
Slope-intercept form is:
Where <em>m</em> = slope and <em>b </em>= y-intercept.
It is stated that the slope of the line is 1.
It is stated that the line includes the point (0, 8)
To find the y-intercept, we can just inverse the slope-intercept form to solve for <em>b</em>.
We know that the point (8, 0) falls on the line, so that's what we'll use for <em>x</em> and <em>y</em>.
Then, we just have to plug those numbers in, as well as the slope.
Simplify.
Simplify again.
Now, we know that <em>b = -8</em>.
All we have left is to plug the slope and y-intercept into the slope-intercept form.
