Vocabulary & Misc.
100
Define slope.
What is rise/run?
Change in y over change in x?
100
What is the equation for point slope form?
y - y1 = m(x - x1)
100
What is the equation for slope intercept form?
What is y=mx+b?
100
What is the equation for standard form?
What is Ax+By=C?
100
Define x intercept
The point where the graph crosses the x axis.
200
What is the slope formula?
What is y2 - y1 / x2 - x1 ?
200
Write the equation of the line that has a slope of 5 and goes through the point (2,-8)
What is y + 8 = 5(x-2) ?
200
Write the equation with a slope of 6 and y-intercept of -8.
What is y=6x-8?
200
Find x and y intercepts of x+4y=8.
The x-intercept is (8,0) and the y-intercept is (0,2).
200
How do you tell the difference between slope intercept form and standard form?
Standard form should always have whole numbers with the x and y on the left hand side of the equation. Slope intercept can have fractions and should be solved for y.
300
From a graph, how do you know if the slope is negative?
It should be going down from left to right
300
Identify the slope and point from this equation:
y - 6 = .25(x + 2)
m = 0.25
point = (-2,6)
300
Graph y = 2x + 3
300
Change to Standard Form:
y - 3 = -4(x - 2)
4x + y = 11
300
How do you graph Standard Form?
Find the x intercept by plugging in 0 for y and solving for x. Find the y intercept by plugging in 0 for x and solving for y.
400
Find the slope between the two points:
(2,5) and (8, 10)
What is 5/6?
400
Write the equation of the line in point slope form given the two points: (3,7) and (9, 10)
y - 7 = 1/2(x-3) OR
y - 10 = 1/2(x - 9)
400
Turn y - 2 = 3(x - 1) into slope intercept form
y = 3x - 1
400
Graph 2x - 3y = 12
400
How do you graph point slope form?
Plot the point then use the slope to plot some more; connect the dots!
