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

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
