Solving Systems of Equations with a Graphing Calculator

What is the first step in solving a system of equations using a graphing calculator?

• Convert the equations to slope-intercept form

• Graph the equations directly

• Enter the equations into the calculator

• Find the point of intersection

How do you clear the RAM on a TI-83 or TI-84 calculator?

• Press 2nd + 9 + 1 + 2

• Press 2nd + 7 + 1 + 2

• Press 2nd + 8 + 1 + 2

• Press 2nd + 7 + 1 + 3

Which button do you press to enter equations into the graphing calculator?

• Y=

• Mode

• Graph

• 2nd

What is the correct way to enter a negative sign in an equation on the calculator?

• Use the subtraction sign

• Use the minus sign

• Use the division sign

• Use the negative sign

What should you do after entering the equations into the calculator?

• Calculate the point of intersection

• Graph the equations

• Clear the RAM

• Turn off the calculator

How do you calculate the point of intersection on the graphing calculator?

• Press Y=, then select 'intersect'

• Press 2nd + Trace, then select 'intersect'

• Press Mode, then select 'intersect'

• Press 2nd + Graph

What is the ordered pair solution for the first example problem?

• (3, 1)

• (2, 2)

• (1, -4)

• (0, 0)

In the second example, what is the slope-intercept form of the equation 4y - 2x = 4?

• y = 2x + 4

• y = 1/2x + 1

• y = -2x + 4

• y = 1/2x - 1

What is the point of intersection for the second example problem?

• (3, 1)

• (2, 2)

• (1, -4)

• (0, 0)

How can you verify the point of intersection using the table of values?

• Check if the x-values match

• Check if the y-values match

• Check if the equations are in slope-intercept form

• Check if both equations have the same x and y values at the point of intersection
