Review Lesson 2-8:
Graph the three inequalities on the same coordinate plane at desmos.com.
Zoom and pan your graph to establish an appropriate viewing window.
Capture a screenshot of your graph.
Upload or paste your screenshot onto the Formative canvas.
Use the canvas tools and a bright, contrasting color to shade in the region of solutions (over the shading that is in the screenshot).
3x-4y\ge16
-5x>8y+4
y<4

Review Lesson 2-3: Identify the slope of the line through each pair of points.

(-2, -4) and (1, 2)
(0, 0) and (5, -3)
(1, 3) and (4, 9)

Review Lesson 1-3: What is the value for a + b - 2c for a = 3, b = 1, and c = -3.

Review Lesson 1-3: Substitute -3 for x in each of the equations. Identify the value of y in each case.

y = -10
y = 8
y = -3
y = -8

10

Vocabulary Review: Classify each equation based on its form.

x + 5y = -3
y = 2x + 10
y - 2 = 5(x - 3)

slope-intercept form
point-slope form
standard form

Classify each item on the left based on the type of system it describes or represents.

You may need to zoom out to see all of the items. You can also place each item from the left column by selecting it (click it) then selecting (clicking on) the category for it.

A system with infinietly-many solutions
A system of 2 parallel lines
A system of 2 perpendicular lines
A system with exactly 1 solution
A system with no solutions

Inconsistent
Consistent and dependent
Consistent and independent

Use Your Vocabulary: Recall the infomation about systems of linear equations below.

Tag each statement as true or false.

false
true

Inconsistent linear systems intersect at two points.
An independent linear system has one solution.
A dependent linear system has no solutions.
Two unique lines with the same slope form an inconsistent system.
