Given two points learn how to determine the slope and y intercept ex 2

The video tutorial explains how to write an equation in slope-intercept form given two points. It introduces the slope-intercept and point-slope forms, emphasizing the usefulness of point-slope form for finding the slope. The tutorial walks through the process of calculating the slope using given points, determining the Y-intercept, and finally writing the equation in slope-intercept form.

What is the primary advantage of using point slope form when given two points?

• It is easier to remember.

• It helps in finding the slope and writing the equation.

• It avoids the use of fractions.

• It directly gives the y-intercept.

When determining the slope, why is it important to use parentheses around the coordinates?

• To simplify the calculation.

• To avoid confusion with signs.

• To ensure the correct order of operations.

• To make the equation look neat.

What is the slope of the line passing through the points (5, 2) and (0, -2)?

• 2/5

• 4/5

• -4/5

• -2/5

How is the y-intercept determined in the slope intercept form?

• By setting x to zero in the equation.

• By using the point where x is zero.

• By subtracting the slope from the y-value.

• By calculating the average of the y-values.

What is the final equation of the line in slope intercept form for the given points?

• y = 4/5x - 2

• y = -4/5x + 2

• y = -4/5x - 2

• y = 4/5x + 2
