SOLUTION: write an equation of the line that passes through the given two points. (-7,8)(-4,11) (7,0)(27,-60) (2,3)(8,0)

Question 23081: write an equation of the line that passes through the given two points.
(-7,8)(-4,11)

(7,0)(27,-60)

(2,3)(8,0)

Let's try the 1st pair of points. The others are worked in the same way.
The two-point form is y-y1 = m (x-x1)
where m= (change in y)/(change in x)
So for your problem m = (11-8)/(-4-(-7)) = 3/3=1
Now the x1,y1 comes from one of your two points; it doesn't
matter which point you pick out. We'll try (-4,11).
Then y-(11) = (1)(x-(-4)
And y-11 = (x+4)
Then y = x+4+11
y = x+15
