CCSS.HSF.IF.A.1

Where the line or curve crosses the y-axis.

• Slope

• X-Intercept

• Y-Intercept

• Range

Where the line or curve crosses the x-axis.

• Slope

• X-Intercept

• Y-Intercept

• Range

The ratio of the change in y-values (rise) with the change in x-values (run). We most often use the formula  $m=\frac{rise}{run}$  or  $m=\frac{change\ in\ y}{change\ in\ x}$  

• Slope

• Range

• Scientific Notation

• Rational

y - y₁ = m(x - x₁)

What do we call this form of a line?

• Slope-Intercept

• Point-Slope

• Standard

y = mx + b

What do we call this form of a line?

• Slope-Intercept

• Point-Slope

• Standard

When lines have the same slope, they are said to be what?

• Parallel
• Perpendicular
