Slope-Intercept Flashcard Corrections

Front

What is the formula to calculate slope from a graph?

Back

Slope = rise over run.

Front

Write the slope-intercept form of a line with a slope of 5 and y-intercept of 2.

Back

y = 5x + 2

Front

How do you graph the equation y = 2x + 1?

Back

Begin at (0,1) on the y-axis, then go up 2 and right 1 to place another point.

Front

What is the slope of the line represented by the equation y = -4x + 3?

Back

The slope is -4.

Front

Write the slope-intercept form of a line with a slope of 1/2 and y-intercept of -3.

Back

y = 1/2x - 3

Front

Where do you start when graphing y = 3x + 4?

Back

Start at (0,4) on the y-axis.

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.

Front

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

Back

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

Front
