Every linear equation graph has a line (True or False)
true
A or B can equal zero (True or False)
true
Variables can be multiplied in a Equation (True or False)
false
The x-intercept is the point where a line crosses the x-axis (True or False)
True
The y-coordinate can not be always zero (True or False)
false
the y-intercept is the point where a parallel crosses x-axis (True or False)
false
The slope refers to the dullness of the line (True or False)
false
the slope of the straight line is defined as the ratio of the vertical rise of the line to its corresponding (True or False)
true
Types of slope
negative, positive, undefined, and zero slope
Standard form
Ax + By = C
Slope-intercept form
y = mx + b
point-slope form
(y - y¹) = m (x - x¹)
Two-point form (Word)
y minus y sub 1, equals y sub 2 minus y sub 1 over x sub 2 minus x sub 1, multiply to x minus x sub 1
Intercept form (word)
x over a plus y over b equals 1

Rene Decartes
The number line is called a
one dimensional coordinate system
A blank or rectangular coordinate system is a plane containing two perpendicular real number lines which intersects at their zero points
cartesian
The x and y-axis divide the plane into a region called —
quadrants
Beginning in the upper right and rotates in a —
counterclockwise direction
the first number of a pair (x-coordinate) measures a horizontal distance from the origin called
abscissa
the second number (y-coordinate) measures a vertical distance from the origin called
ordinate
(+,+)
quadrant 1
(-,+)
quadrant 2
(-,-)
quadrant 3
