Writing slope intercept form
Write an equation using slope intercept form using the following:
m=15, b=-7
y=15x-7
(8,7) and (2,12)
-5/6
Which letter represents slope in the slope intercept formula
y=mx+b
m
Write the slope formula
y2-y1/x2-x1
Solve
x+4=10
x=14
Write an equation using slope intercept form using the following:
m=-1/2, b=3.5
y=-1/2x+3.5
(12,-10) and (15,-8)
2/3
Which letter represents the y-intercept in the slope intercept formula
b
Which comes first when writing slope rise or run
Rise/Run
You can't run before you rise
2x+5=21
x=8
A line has a slope of -9 and passes through the origin, what is the equation in slope intercept form?
y=-9x
or y=-9x+0
(3, 9) and (6, 14)
5/3
How many types of slope are there?
4
Positive, negative, zero and undefined.
What is the y intercept?
It is where a line crosses the y axis when the value of x is 0
3x-4=26
x=10
Charlie writes said that the y-intercept for a line was -7 and the slope is 3/8. Write the equation to represent Charlie's line.
y=3/8x-7
x:2, 6, 10, 14
y: 8, 28, 48, 68
m = 5
What is slope
The change in y over the change in x
Rise over run
Write an equation in slope-intercept form that meets the given criteria.
a. A negative slope and passes through the
origin
y = -3x or y=-3x+0
Equations have equal signs and must be balanced, while inequalities compare two things and show things are not equal
If a line crosses through the y-axis at 8 and rises 4 and runs 5, write the equation to represent the line in slope intercept form.
y=4/5x+8
(-1, 3) and (5, -5)
-4/3
The slope of a vertical line will always be _______________.
Undefined
1. Harper is going to create a graph of the
equation y = -0.5x + 12. Which of the following
will be true about the graph?
a. The graph will contain the origin.
b. The graph will increase from left to right.
c. The graph will cross the x-axis at (12, 0).
d. The graph will have a slope of -0.5.
d. The graph will have a slope of -0.5.
