The slope of a line is the ratio of rise to run for any two points on the line

The x-intercept of a line is the value of y where the line crosses the y-axis
What is x-intercept
200
Tell if its linear
y=x^3
Not linear

What is rise?
The rise is the difference of the y-values of two points on a line

What is a literal equation
A literal equation is an equation with two or more variables.
300
Tell if it's linear
y=1/4x-1

What is A solution of a system of equations
A solution of a system of equations is a set of values that are solutions of all of the equations. If the system has two variables, the solution can be written as ordered pairs
400
Tell if it's linear
y=x^2-12
Not linear

find the slope
(2,5) and (3,6)
The slope is 1
400
find the y-intercept(x=0)
3x+4y=12
The y-intercept is 3

What is a system of equations
A system of equations is a set of two or more equations that contains two or more variables.
500
Tell of its linear
y=1/3x^2
Not linear
500
Fine the slope
(-2,-2) and (-4,1)
the slope is
-3/2
500
Write the equation of the line that passes through each pair of points in slope-intercept form.
(0,3)and(2,-5)
y=-4x+3

what is a direct variation?
a direct variation is a linear function that can be written as y=kx, where k is a nonzero constant called the constant of variation
