Exploring Linear Functions in Algebra 1 EOC Review

The video tutorial covers linear functions, focusing on slope and rate of change, including types of slopes such as positive, negative, zero, and undefined. It explains slope-intercept form, point-slope form, and standard form, providing examples for each. The tutorial also covers graphing linear inequalities, detailing how to determine the type of line and shaded regions. The session concludes with an offer of support for further questions.

What formula is used to calculate the slope of a line given two points?

• (X2 + X1) / (Y2 + Y1)

• (Y2 + Y1) / (X2 + X1)

• X2 - X1 / Y2 - Y1

• Y2 - Y1 / X2 - X1

How is the point-slope form of a line's equation written?

• y - y1 = m(x - x1)

• y = mx + b

• ax + by = c

• y + y1 = m(x + x1)

What does the standard form of a linear equation look like?

• y = mx + b

• ax + by = c

• y - y1 = m(x - x1)

• x/y = m + b

What type of line is used to graph y > mx + b?

• Thick line

• Solid line

• Dashed line

• Dotted line
