I will be adding a lot I would like help within the he it is due at 11:59 in the USA

Step-by-step explanation:

Given points (4, -8) and (8, 5):

Let (x1, y1) = (4, -8)

(x2, y2) = (8, 5)

Substitute these values into the slope formula:

m = (y2 - y1)/(x2 - x1)

Therefore, the slope of the equation is 13/4.

Next, to find the y-intercept, use one of the given points (4, -8) and the slope. Substitute these values into the slope-intercept form to solve for the y-intercept, b:

y = mx + b

-8 = 13 + b

Subtract 13 from both sides:

-8 - 13 = 13 - 13 + b

-21 = b

Therefore, given the slope, , and the y-intercept, b = -21:

The linear equation in slope-intercept form is:

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
