Write Linear Equation using Slope and y-intercept

Front

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

Back

The y-intercept of the line.

Front

How do you write the equation of a line given the slope and y-intercept?

Back

Use the formula y = mx + b, where m is the slope and b is the y-intercept.

Front

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

Back

y = -3x - 3.

Front

If a line passes through the point (0,-5) and has a slope of -8, what is the equation of the line?

Back

y = -8x - 5.

Front

What is the equation of a line with a slope of -1 that passes through (0,8)?

Back

y = -x + 8.

Front

If a line has a slope of 2 and passes through (0,6), what is the equation of the line?

Back

y = 2x + 6.

Front

What is the slope of a line that is horizontal?

Back

The slope is 0.

Front

What is the slope of a line that is vertical?

Back

The slope is undefined.

Front

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

Back

Use the formula m = (y2 - y1) / (x2 - x1).

Front

What does the slope of a line indicate about its steepness?

Back

A larger absolute value of the slope indicates a steeper line.
