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 :)

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
