Solving Linear Equations

100

5.9 = y - 2.7

y=8.6

200

(3/2)(x - 2) - 5 = 19

x = 18

300

(3/8)=(12/b)

b = 32

400

|2x - 19|=|4x + 1|

x = -10 or x = 3

500

Solve for y: a = 9y + 3yx

y = a/(9 + 3x)

Solving Linear Inequalities

100

Write the sentence as an inequality: A number x is greater than 100. 

x > 100

200

Solve and show solution on a number line:

x - 4 < -5

x < -1

300

Solve and show solution on a number line:

-16 < (8/3)x

x > -6

400

Solve and graph the solution on a number line

5y + 9 < 4

y < -1

500

Write the following as an inequality and graph on a number line:

A number no less than -1.5 and fewer than 9.5

-1.5< (SHOULD BE LESS THAN OR EQUAL TO) x< 9.5

Graphing Linear Functions

100

Put the following equation into slope intercept form: 

y - 7= -3x. Will the line be sloping upwards or downwards on the graph?

y = -3x + 7, Sloping downwards

200

Is the following equation linear or non-linear?

18x - 2y = 26

Linear!!

300

Find the function when x = -2: 

f(x) = 12 - 2x - 5.8

F(-2) = 10.2

400

f(x) = 4x + 15, f(x) = 7. Find the x value so the function has the given value. 

x = -2

500

Find the slope and y-intercept of the line 0= 4.5 - 2y + 4.8 x and determine if it's a function.

slope= 2.4

y-intercept= 2.25

yes, it is a function because every input has exactly one output. 

Writing Linear Functions

100

Put the equation in slope intercept form:

12y - (- 24x) = 32

y = -2x + 8/3

200

Write an equation in slope intercept form that passes through the following points: (7, 2) and (12, 2).

y = 2

300

Determine if any of these lines (that go through the following points) are parallel or perpendicular to one another:

line a: (0, 4) and (4, 3)

line b: (0, 1) and (4, 0)

line c: (2, 0) and (4, 4)

line d: (6, 3), (2, 2)

Lines a and b are parallel to each other.

400

When using technology to perform linear regression, what does the "r" value represent?

Correlation Coefficient

500

What are residuals?

A residual is the difference between the y-value of a data point and the corresponding y-value found using the line of best fit.
