HW: Standard to Slope-intercept Form & Horiz/Vert Lines

Front

What type of line has an undefined slope?

Back

Vertical line

Front

What type of line has a slope of 0?

Back

Horizontal line

Front

What is the equation of a line with a slope of 0 that passes through the point (6, 7)?

Back

y = 7

Front

If a line passes through the points (4, 5) and (4, 7), what type of line is it?

Back

Vertical line

Front

What is the equation of a line with an undefined slope that goes through the point (-3, 5)?

Back

x = -3

Front

What is the slope-intercept form of a line?

Back

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

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

Front

What does a positive slope indicate about a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

The line falls from left to right.

Front

What is the y-intercept of a line?

Back

The point where the line crosses the y-axis (x=0).
