Answer:

Step-by-step explanation:
2x + 5y = 6 --------( 1 )
5x - 2y = 9 --------( 2 )
_____________
( 1 ) x 5 => 10x + 25y = 30 -----------( 3 )
( 2 ) x 2 => 10x - 4y = 18 ----------- ( 4 )
______________
( 3 ) - ( 4 ) => 0 + 29y = 12

Substitute y in ( 1 ) =>

Answer:
A. Would be your answer
Step-by-step explanation:
7 plus a number n is 7+n, so B and D are already incorrect.
The phrase “and then multiply” suggests parenthesis be around the numbers/variables you would need to do first, so that excludes C.
Making A. your only answer left

Answer:
y + 1 = -2/7 (x + 4)
Step-by-step explanation:
Find the slope using y₂ -y₁ /x₂ -x₁
m = -3 + 1 / 3 + 4
m = -2/7
Plug the m, x and y into the point slope equation y - y₁ = m ( x - x₁)
y + 1 = -2/7 (x + 4)
