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.

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 :)

mean, 40.6
