Solving Linear Equations
5.9 = y - 2.7
y=8.6
Write the sentence as an inequality: A number x is greater than 100.
x > 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
Put the equation in slope intercept form:
12y - (- 24x) = 32
y = -2x + 8/3
Which 8th grade teacher is a Packer fan?
Ms. Hintzman
(3/2)(x - 2) - 5 = 19
x = 18
Solve and show solution on a number line:
x - 4 < -5
x < -1
Is the following equation linear or non-linear?
18x - 2y = 26
Linear!!
Write an equation in slope intercept form that passes through the following points: (7, 2) and (12, 2).
y = 2
Which 8th grade teacher started their teaching career in Texas?
Ms. O'Connell
(3/8)=(12/b)
b = 32
Solve and show solution on a number line:
-16 < (8/3)x
x > -6
Find the function when x = -2:
f(x) = 12 - 2x - 5.8
F(-2) = 10.2
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.
What does Mr. Haight say at the end of every Monday morning meeting?
Be kind to yourself, be kind to others.
|2x - 19|=|4x + 1|
x = -10 or x = 3
Solve and graph the solution on a number line
5y + 9 < 4
y < -1
f(x) = 4x + 15, f(x) = 7. Find the x value so the function has the given value.
x = -2
When using technology to perform linear regression, what does the "r" value represent?
Correlation Coefficient
What is written on Mr. Robnick's coffee mug
Students' Tears
Solve for y: a = 9y + 3yx
y = a/(9 + 3x)
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
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.
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.
What are the names of the Melton's dogs?
