Solving linear equations by graphing pdf
Web17. In a piggy bank, the number of nickels is 8 more than one-half the number of quarters. The value of the coins is $21.85. a) Create a linear system to model the situation. b) If the number of quarters is 78, determine the number of nickels. 18. a) Write a linear system to model this situation: A large tree removes 1.5 kg of pollution from the air each year. WebStep 1: Observe the equations. They are of the form y = mx + b, where m is the slope. Step 2: Find the intercepts of the graph of the given equations. Step 3: First, find the x-intercept of first equation y = x - 4 by substituting x = 0, we get y = -4. For y = 0, x = 4.
