Question

Help I need help graphing three points

Answer 1

(2,-1) ; (-1, 4) ; ( 5 , -6)

Explanation:

-5x - 3y = -7

Put x = 2 , -5*2 - 3y = -7

-10 -3y = -7

-3y = -7 + 10

-3y = 3

y = 3/-3

y = -1

(2,-1)

Put x = -1 ; -5 *-1 -3y = -7

5 - 3y = -7

-3y = -7 - 5

-3y = -12

y = -12/-3

y = 4

(-1, 4)

Put x = 5, -5*5 -3y = -7

-25 - 3y = -7

-3y = -7 + 25

-3y = 18

y = 18/-3

y = -6

( 5 , -6)
