In this exercise we have to use slope knowledge to calculate the formula we found for this graph, like this:
[tex]y = (-1/2)x + 1[/tex]
Knowing that the general formula for writing make slope-intercept form is;
[tex]y - y_1 = m(x - x_1)[/tex]
From the question, we know that:
Put the number to the formula:
[tex]y - y_1 = m(x - x_1)\\y - (-4) = -1/2(x - 10)\\y + 4 = -1/2 (x - 10)\\y + 4 = (-1/2)x + 5\\y = (-1/2)x + 1[/tex]
