Key Features of Linear Graphs
The point where a graph crosses the y-axis
y-axis
In the equation y=mx+b the letter representing the y-intercept is
b
What type of numbers A, B, and C (other word for whole number)
integers
The equation of a vertical line passing through the point (5,-3).
x=5
The inequity symbols used to represent the mathematical phrase "at most"
< with a line under it to show its less than or equal to.
The measure of the steepness of a line (rise over run)
The slope of the line given by the equation y=-3x+8
-3
The standard form of the linear equation y=-2/3x+4
2x+3y=12
The equation of a horizontal line passing through the point (2,8).
y=8
The direction you shade when the inequality is y>3x-4
above the slope
The point where a line crosses the x-axis
x-intercept
The equation of a line with a slope of 5 and a y-intercept of -2
y=5x-2
The standard form of the linear equation 2x=y+9
2x+y=9
The equation of a line parallel to y=-4x+2 that passes through the origin (0,0)

What type of boundary line do you draw when inequality have a line under it.
solid line
The slope value of a perfectly horizontal line
zero
The point-slope form equation for a line passing through (4,1) with a slope of 2
y-1=2(x-4)

Tickets cost 10$ each, you also must spend a 5$ entree fee, but you can spend a maximum of 50$
10x+5<50 (the inequality is supposed to have a line under it to represent that its less than or equal to)
A slope that is perfectly vertical
undefined
The slope-intercept form of equation y-3=4(x-2)
y=4x-5
The standard form equation of a line passing through the points (1,4) and (3,9).

The equation of a line with a undefined slope that passes through the point where the line y=3x-4 and y=-2x+11 intersect.
x=3
The inequality representing a shaded region that excludes the origin (0,0) using the boundary line y=2x-5
y<2x-5
