Slope Basics
In a linear equation of the form, y = mx +b, this letter represents the slope
What is m?
This is the y-coordinate of the point where the graph of a line crosses the y-axis.
What is the y-intercept?
This is a name for the form y = mx + b.
What is slope-intercept form?
Parallel lines have this in common about their slopes.
If a line goes downhill from left to right, the slope is this sign.
What is negative?
To graph the line y = 2x + 3, you would plot this point first.
What is (0, 3)?
The slope-intercept form of the equation with a slope of -3/4 and y-intercept of 6
What is y = -3/4x + 6?
These lines have opposite signs and are reciprocals of each other?
What are perpendicular lines?
This is the linear equation for y earnings, if you earn $5 per hour of babysitting for x hours and a $10 bonus.
A horizontal line has this type of slope.
What is zero?
The slope of the line y = -3x + 5 is graphed by moving this number of units and in what direction?
What is down 3 and over to the right 1?
The line with equation y - 2= 3(x - 1) is written in this form.
What is point-slope form?
What is - 2?
This is the equation for the total cost, y, of renting a car and driving it x miles if the rental company charges $25 per day and $0.20 per mile driven.
What is y = 0.20x + 25?
A vertical line has this type of slope.
What is undefined?
To graph the line, 4x + 5y = 20, you first do this to convert its form.
What is solve for y?
The point-slope form of the line with a slope of -4 and passing through the point (-3, 2).
What is y - 2 = - 4(x + 3)?
The slope of a line perpendicular to this line, y = -5/7x + 2
What is 7/5?
This is the total fare for a 5-mile taxi ride in which the charge is $3 plus $2 per mile.
What is $13?
This is the slope of the line that passes through (0,-1) and (1,3).
What is 4?
The first two points needed to graph a line with a given slope of 2/3 and a y-intercept of 3.
What is (0,3) and (3,5)?
The slope-intercept form of the equation of the line passing through the given points, (3, 7) and (5, 13).
What is y = 3x -2?
The slope of the line parallel to this line, 2x - 5y = 10.
What is 2/5?
This is the slope-intercept equation of the line with a y-intercept of 6 that passes through the point, (3, 12).
What is y = 2x + 6?
