10x - 7y = -1....multiply by -1 to make that -7y positive
-2x - 7y = -25
------------------
-10x + 7y = 1 (result of multiplying by -1)
-2x - 7y = -25
-----------------add
-12x = - 24
x = 2
-2x - 7y = -25
-2(2) - 7y = -25
-4 - 7y = -25
-7y = - 25 + 4
-7y = - 21
y = 3
solution is : (2,3)
Answer:
y=2x-4
Step-by-step explanation:
y-y1=m(x-x1)
y-10=2(x-7)
y-10=2x-14
y=2x-14+10
y=2x-4
