All flour from five bags with 3 8 lbs of flour in each was divided into equal parts to make 7 loaves of bread. how can you calculate the amount of flour used for each loaf? select all that apply. (a) 3 8 · 7 5 (b) 3 8 · 5 7 (c) 3 8 ÷7·5 (d) 3 8 ·7÷5 (e) 3 8 ÷5·7 (f) 3 8 ·5÷7

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
