How can you write the equation for a linear function if you know only two ordered pairs for the function?
Use the two ordered pairs to find the slope, m. Then substitute m and one set of ordered pairs into y=mx+b, solve for b.
Find the y-intercept. Then use an ordered pair and the y-intercept to find the slope
Find the x-intercept, Then use an ordered pair and the x-intercept to find the slope.
