Graphing equations
What is a liner equation?
Its an equation where both terms have to be consistent.
What is a form that can also be used for an equation of a straight line?
slope intercept form
What is the written equation for the point slope form?
(y - y1) = m(x - x1))
What is a positive thing for a standard form of a line?
That it can help you with vertical lines and horizontal lines
How can you find a equation with two points?
Calculate the slope from 2 points. Substitute either point into the equation. Solve for b, which is the y-intercept of the line. Substitute b, into the equation from step 2.
What is the liner equation in written form?
y = mx + b
What does the slope form help us with?
Graphing things
What is the purpose of the point slope form of a line?
To find out the equation for the slope
Is it easier or harder to get Both equations in standerd form?
Easier
What is the slope formula?
Identify two points on the line. Select one to be (x1, y1) and the other to be (x2, y2). Use the slope equation to calculate slope.
What does the m represent in the equations?
Its the rate of change or the slope
How can you use slope intercept form to figure out an equation?
You can find out the changes over the course of time and the value
Why is it important to get the right equation?
So that you get the right coordinates on the graph
Why do you use standard form?
It helps you break down the numbers
Whenever your making a point you need two things what are there?
A point and a slope
What is a slope?
Its how fast the line moves up or down
True or false: Straight line equations have no exponents?
True
Is it possible to convert the slope formula into the point slope formula.
yes
Why is it important to keep everything balanced while solving the equations?
So that you solve you equations the right way
What is the slope of the line?
It is the direction or characteristic of a line
What does the b stand for in the slope equation?
it stands for the y intercept of the function
Why is it called the slope intercept form?
Because the slope-intercept form because "m" is the slope and "b" gives the y-intercept.
True or false : The point slope form isn't the only type of linear equation.
false
True or false : When your solving the equations you have to make sure everything is equal
true
How do you use slope?
Plot a point on the y-axis. Look at the numerator of the slope. Look at the denominator of the slope. Plot your point. Repeat the above steps from your second point to plot a third point if you wish. Draw a straight line through your points.
