example: the line is y = ax + b
The line go through 2 points ( -4 ; 0 ) and ( 0 ; -2 )
So:
- -2 = 0a + b => b = -2
- 0 = -4a + (-2) => a = 2/-4 = -1/2
The line is y = -1/2x - 2 ( i'm not sure)
Answer: a
Ok done. Thank to me :>
Answer:
i think options are incorrect
x is 20 here
you can verify by putting value
Answer:

Step-by-step explanation:





<span>x=y+2
2y=x-1
substitute </span>x=y+2 into 2y=x-1
2y=x-1
2y=y+2 -1
2y - y = 1
y = 1
<span>x=y+2
</span><span>x=1+2
x=3
answer
x = 3 and y = 1</span>
