4.3-4.4 Flashcard Review Assignment

Front

In the equation y=mx+b, what does the m represent?

Back

m represents the slope of the line.

Front

Write the equation in slope-intercept form: -10x + 2y = 14

Back

y = 5x + 7

Front

What is the Linear Equation of the graph? (Choose from the options) y=-\frac{1}{2}x-6, y = 2x - 6, y = -2x -6, y = -6x - 2

Back

y=-\frac{1}{2}x-6

Front

Write the equation of a line that passes through the point (4, -1) and has a slope of 2.

Back

y = 2x - 9

Front

Which equation matches the graph? (Choose from the options) y = 2x, y=\frac{1}{4}x+2, y = 4x + 2, y = -2x

Back

y=\frac{1}{4}x+2

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope m is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by b in the equation y = mx + b.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

A slope of 0 indicates that the line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

An undefined slope indicates that the line is vertical.
