Ineed on these plz i will give brainliest! question 1 

(8.02 mc)

 which of the following graphs shows a pair of lines that represents the equations with the solution (3, −6)? 

 a coordinate grid is shown from negative 8 to positive 8 on the x axis and also on the y axis. a pair of lines is shown intersecting on ordered pair 6 units to the left and 3 units up.

question 2

 (8.03 mc)

 two equations are given below: 

m + 3n = 10
m = n − 2

what is the solution to the set of equations in the form (m, n)? 

(1, 3) 
(2, 4) 
(0, 2) 
(4, 6)
 question 3

 (08.01 mc)

 the graph shows two lines, a and b: 

a graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. a straight line labeled a joins the ordered pair 3, 0 and the ordered pair 0, 6. another straight line labeled b joins the ordered pair 0, 0 and the ordered pair 5, 5.

based on the graph, which statement is correct about the solution to the system of equations for lines a and b? 

 (0, 6) is the solution to both lines a and b. 
(0, 6) is the solution to line b but not to line a. 
(2, 2) is the solution to both lines a and b. 
(2, 2) is the solution to line a but not to line b.
