what is the equation of this line im stupid?????

(-8,0) and (0,5)

Let's get the slope, first

Subtract the y's    so we have  5 - 0  = 5

Subtractt the x's in the same order    0- (-8)  = 8

Put the first result over the other  .. 5/8 ...  this is the slope = m

Using one of the points - I'll select (-8, 0) -   we can use the point-slope form

y - y1 = m(x - x1)      and using (-8,0) for (x1, y1)

y - 0  =  (5/8)(x - (-8))

y = (5/8)(x + 8)

y = (5/8)x + 5

And there's the equation !!!
