Is writing an answer......
Answer:

Step-by-step explanation:
2)
a) elimination method
b) substitution method
c) substitution method
For the first part we can elimate the y variable by subtracting the equations. We can then find the value of x.
For the second part we can substitute y as 2x+5 in the second equation and solve for x.
For the third part we can substitute y as 4x+3 in the first equation and solve for x.
3)

You answered correctly.
(a brainliest would be appreciated)
Milli is the answer because it just is so yeah
Point-slope form :-
... y = mx + b
<em>In this equation, 'm' represents the slope and 'b' represents the y-intercept. </em>
Given :-
... y = -1/7x + 2
<u><em>Hence, the slope is -1/7 and y-intercept is 2 or ( 0 , 2 ) </em></u>
Hope it helps!!
