Linear Equations TEST

Front

What is the formula to calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What is the slope of the line that passes through the points (5,7) and (-3,4)?

Back

3/8

Front

What is the slope of the line that passes through the points (2, 4) and (6, 12)?

Back

2

Front

What is the y-intercept of the line represented by the equation y = -2x + 6?

Back

6

Front

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

Back

y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Front

Convert the equation y = -2x + 1 to slope-intercept form.

Back

The equation is already in slope-intercept form: y = mx + b.

Front

What does the slope of a line represent in a graph?

Back

The slope represents the rate of change of y with respect to x.

Front

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

Back

The line is horizontal.

Front

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

Back

The line is vertical.

Front

What is the y-intercept of the line represented by the equation y = 3x - 5?

Back

-5
