Write an equation of the line that passes through a pair of points:

(-5,-2) (4,5)

jennithemeani · Answer

Start by finding the slope $$y^2-y^1/x^2-x^1$$

jennithemeani · Answer

y^2 is 5 and Y^1 is -2 
X^2 is 4 and X^1 is -5 so
$$5+2\div 4+5$$

jennithemeani · Answer

Add them together to get 7/9 This is your slope
Now that you have your slope you have to find B
So use y=mx+b and fill it in

Take y and x from your equation (Make sure you pick the same y and x y^1 goes withX^1)
5=7/9(4)+b
5=28/9+b (mutiply 28/9 on both sides)
28/9 (5)= B
B=140/9

So you then make it y=7/9(x)+140/9
