Solve: 4x + 7 = 31
x = 6
Are the set of points a function if not tell me why? : (1, 2), (2, 3), (2, 4), (3,5)
Not a function because there are two x=2. We cant have repeating x-values
What do we draw to help us remember if a slope is positive or negative? (Draw it)
m mountain
What is the equation of a line in slope intercept form that has a slope of 3 and crosses the y-axis at -5?
y=3x-5
What is rate of change?
Solve: 2(3x - 4) = 34
x = 7
Are the set of points a function if not tell me why? (-2,12), (1,10), (5,8), (-3,-4), (-4,-4)
Yes
Explanation: It is a function because none of the x values are repeating
What is the slope of the Function
y-x/9=12
m=1/9
Write the equation of a line that has a slope of -4 and passes through the point (2,-3)
y+3=-4(x-2)
What are other words used for zeros of a functions?
X-intercepts, Solutions
Solve: 3x + 3 - 2x = 21
x = 18
Is the given table a Function if not explain why?
Not a Function because there are repeating x-values. x=-3
Parallel lines have what?
Same slope
slope intercept form:
y=-3x+4
Standard form:
3x+y=4
Zero
Solve:
3p - 1 = 5( p - 1) - 2(7 - 2p)
p = 3
Determine if the following graph represents a function?
Yes because it passes the vertical line test
What is the slope of a line that is passing through the given points?
(8, -1) and (-5, 6)
m=-7/13
What is the linear function of function table below?
y=x-8
What is the equation to a Exponential Function?
y=a*b^x
Solve:
3/7x+6=9
x = 7
State if the mapping represents a function
Yes this is a function because there is only one input per output
What is the slope of a line that is passing through the given points? Write the equation of the line in standard form.
(4, 2) and (1, -7)
m=3
Standard form:
3x-y=10
Write the equation of the line in slope-intercept form for the line passing through (3,9) and (5,4)
y=-2.5x+16.5
y=-5/2x+33/2
What is the Standard form of a Linear Function?
Ax+By=C
