Question

Your friend was absent the days that the following formulas were introduced. Write a detailed letter to your friend explaining them. 1. Slope formula 2. Slope-intercept form 3. Standard form. Address what the forms are, when they are used, and how they are used. Give detailed examples.

Answer 1

1. Slope formula = Change in y ÷ change in x.

i.e slope(m) = (Δ means change in)

2. Slope-intercept form is representing equation of a straight line on cartesian plane in the form y = mx + c. Where (m) is the slope of that line and c is the y-intercept.

3. Standard form - is writing numbers in the form of number times ten to power of an exponent. This is also referred to as scientific notation form.

Example:

To write 512 in standard form would be 5.12 × 10²

II hope this helps :)

Answer 2

Answer plus step-to-step explanation:

1. Slope formula = Change in y ÷ change in x.

i.e slope(m) =
`(Δx)/(Δy)` (Δ means change in)

2. Slope-intercept form is representing equation of a straight line on cartesian plane in the form y = mx + c. Where (m) is the slope of that line and c is the y-intercept.

3. Standard form - is writing numbers in the form of number times ten to power of an exponent. This is also referred to as scientific notation form.

Example:

To write 512 in standard form would be 5.12 × 10²
