Graphing a line from an equation

Front

What does 'm' represent in the equation y=mx+b?

Back

Slope

Front

Where do we begin when graphing a line from an equation?

Back

Put a point on the y-intercept.

Front

Which line has a slope of 0?

Back

A horizontal line.

Front

What does 'b' represent in the equation y=mx+b?

Back

Y-intercept

Front

What is the slope of a line that rises 2 units and runs 1 unit?

Back

2 (rise/run = 2/1)

Front

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

Back

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

Front

What is the equation of a line with a slope of 3 and a y-intercept of 1?

Back

y = 3x + 1

Front

If a line passes through the points (1, 2) and (3, 6), what is its slope?

Back

2

Front

What is the first step in graphing the line y = 2x + 1?

Back

Plot the y-intercept at (0, 1).

Front

What does a negative slope indicate about a line?

Back

The line decreases as it moves from left to right.
