Make sure that you have the following things with you at the computer before you begin.
1. pencil 2. paper 3. calculator 4. notes from 7.1 - 7.3
You must turn in your work when you are finished. State the solution: State the solution: The equation listed is in what form?
y = 2x - 5 standard form slope-intercept form What information do you pull out of the equation? y = 2x - 5 slope and y-intercept x-intercept and y-intercept y = 2x - 5
State the slope: State the y-intercept: Where do you start the graph? slope y-intercept The equation listed is in what form?
3x - 2y = 12 standard form slope-intercept form What information do you pull out of the equation? 3x - 2y = 12 slope and y-intercept x-intercept and y-intercept Find the x-intercept for the equation above: 3x - 2y = 12 How do you find the x-intercept? it is already there: 3 x = 0 and solve for y y = 0 and solve for x Find the y-intercept for the equation above: 3x - 2y = 12 How do you find the y-intercept? it is already there: -2 x = 0 and solve for y y = 0 and solve for x Solve the following system of equations by substitution. y = 2x + 5 4x + y = 17 Solution: Solve the following system of equations by linear combination:
-30x + 4y = -20 5x - 4y = -30 Solution: On your paper, Solve the following systems of equations by linear combination:
6x + 2y = 2 -3x + 3y = -9
