What is the constant of variation?
4x + 2y = 18 is in what form?
What is standard form?
The equation of a line with a slope of 4 and through the point (0, -5).
What is y = 4x - 5?
The slope of a line parallel to one with a slope of -5.
What is -5.
A scatter plot where a line of best fit is appropriate has this type of association.
What is linear?
A direct variation with the y-values being 1/2 of the x values.
What is y = (1/2)x?
This form is not y=-4x + 2 or 5x - 2y = 8
What is point-slope form?
A scatter plot whose points are all close to the line of best fit has this type of association.
What is strong association?
A direct variation through the points (6, 24) and (-8, -32).
What is y = 4x?
It is y = 2x - 5 in standard form.
What is -2x + y = -5?
It is 8x - 6y = 1 in simplified slope-intercept form.
What is y = (4/3)x - (1/6)?
Equation of a line through the points (-2, 5) and (6, -3)
What is y = -1x + 3?
The line described by y = 4x - 2 and this other line through the point (0, -8) can be described as being parallel.
What is y = 4x + 8?
Describe the given scatter plot using all three types of association.
What is nonlinear, neither, and strong?
Equation of a line through the points (-7/3, 4) and (-6, 3/8).
What is y = (87/88)x + (555/88)?
This computational method can be used to say that two lines are perpendicular.
What is checking to see if the product of the two slopes is -1?
What is a good equation for the given scatter plot? Give answer with slope and y-intercept to nearest tenth.
What is y = -13.3x + 116.7?
