Question

How do I graph these equations?

Answer 1

The problem says: 
Solve the pair of equations by graphing.
Here's how:

In each pair:

-- Solve the first equation for 'y'.
   (Put it in the form of  y=m₁x+b₁ .)
-- Graph the straight line with slope=m₁ and y-intercept=b₁ .

-- Solve the second equation for 'y'.
   (Put it in the form of  y=m₂x+b₂ .)
-- Graph the straight line with slope=m₂ and y-intercept=b₂ .

-- The solution to the pair of equations is the point
where the two lines cross.
