4.2 Homework Problems: Graphing Linear Equations

1. Graph the following lines by finding at least 2 ordered pairs and plotting them on the graph provided

a.  x + 1 = 2

b.  4x = 3y – 5

c.  [latex]\frac{2}{3}[/latex] x – y = 4

2. The relationship between Celsius and Fahrenheit is linear. Convert °C (Celsius) to °F (Fahrenheit) using the following equation

Convert °C (Celsius) to °F (Fahrenheit) using the following equation.

°F = ( [latex]\frac{9}{5}[/latex] * °C ) + 32   or  °F = (1.8 * °C ) + 32

Fill in the following table and then graph the ordered pairs on the graph provided. Scale the graph accordingly
