Understanding Slopes in Linear Equations

The video tutorial guides viewers through solving a practice SAT Math question focused on identifying the slope of a line from given linear equations. It explains how to convert equations from standard form to slope-intercept form to find the slope. The tutorial highlights equations that are easier to solve and provides step-by-step solutions for each, emphasizing the importance of understanding the slope-intercept form. The video concludes with a review of additional equations to reinforce the learning process.

What is the standard form of a linear equation?

• y = mx + b

• x = my + b

• y = ax + c

• ax + by = c

Which form of a linear equation allows you to easily identify the slope?

• Quadratic form

• Point-slope form

• Slope-intercept form

• Standard form

Why are equations b and c easier to solve for y?

• They have a constant term on the left.

• They have a negative coefficient for y.

• They have a positive coefficient for y.

• They have a positive coefficient for x.
