# Algebra Problems on Linear Equations

1. Graph this equation.

y = 3/2x +1

2. Determine whether each pair of equations represents parallel lines.

y = -5/4 +1,

y = 5/4x +3

4. Solve using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.

x + 8y = 8

9x - 5y = -5

5. Translate the problem into a pair of linear equations in two variables. Solve the equations using either elimination or substitution. State your answer for both variables.

The perimeter of a rectangle is six times the width. If the length were increased by 4 inches and the width were increased by 7 inches, then the perimeter would be 160 inches. What are the length and the width?

6. Translate the problem into a pair of linear equations in two variables. Solve the equations using either elimination or substitution. State your answer for the specified variable.

From a point on a river, two boats are driven in opposite directions, one at 10 miles per hour and the other at 8 miles per hour. In how many hours will they be 54 miles apart?

7. Translate the problem into a pair of linear equations in two variables. Solve the equations using either elimination or substitution. State your answer for both variables.
