Consider the following system of equations given in slope-intercept form.


y = −1

3

x + 17,


y = 5x - 23


Use the graphing calculator to determine the best window range to find the point of intersection.

–10 Less-than-or-equal-to x Less-than-or-equal-to 10, –10 Less-than-or-equal-to y Less-than-or-equal-to 10

–20 Less-than-or-equal-to x Less-than-or-equal-to 0, –20 Less-than-or-equal-to y Less-than-or-equal-to 0

0 Less-than-or-equal-to x Less-than-or-equal-to 20, 0 Less-than-or-equal-to y Less-than-or-equal-to 20

20 Less-than-or-equal-to x Less-than-or-equal-to 40, 20 Less-than-or-equal-to y Less-than-or-equal-to 40

answer: c.0 Less-than-or-equal-to x Less-than-or-equal-to 20, 0 Less-than-or-equal-to y Less-than-or-equal-to 20

Option c. The range of window for the data is given as 0 Less-than-or-equal-to x Less-than-or-equal-to 20, 0 Less-than-or-equal-to y Less-than-or-equal-to 20

How to solve for the range of the data

We have the equation to be

y = −3x + 17,

and y = 5x - 23

We have to make the two equations to be equal

This would then give us

−3x + 17 = 5x - 23

The next step is to take the like terms

3x - 5x = -23-17

-2x = -40

From you we have to divide by -2

x = 20

The range would be written as

0 ≤ x ≤ 20, 0 ≤ y ≤ 20
