PLEASE HELP ASAP Determine the x-intercept, y-intercept, and slope of the line described by −3x+7y=−21

Please state what the x-intercept, y-intercept, and slope is!!!

Slope = 3/7

y - intercept: y = -3

x - intercept x = 7

Step-by-step explanation:

You have to cimplify the equation in terms of y

-3x +7y= -21

7y= 3x-21

y = 3/7x - 3

SLOPE: It is whatever x is mutlipliedby

slope would be 3/7

Y intercept: you need to plug in x=0

y = 3/7(0) - 3

Zero multipled by anything is zero so you are left with

y = -3

X intercept: plug in y = 0

0 = 3/7x - 3

Move the -3 to the other side

3 = 3/7x

Multiply by the reciprocal 7/3

x = 7/3 * 3

x = 21/3

x = 7

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

i would say b) is your answer

sorry if im wrong
