Equations and ordered pairs Chapter 1 Section 7

Finding ordered pairs Steps to find ordered pairs: 1. Plug in the number for x into the equation for x 2. Simplify the expression (follow order of operations) 3. The solution is the y- value. 4. Write the solution as a point

Example y = 2x+1 Input X Work Output Y -2 -1 1 2

Example y = -3x+2 Input X Work Output Y -2 -1 1 2

Example y = 5x – 1 Input X Work Output Y -2 -1 1 2

Example y = 8x – 12 Input X Work Output Y -2 -1 1 2

Example y = -4x Input X Work Output Y -2 -1 1 2
