Answer:
{1}
Step-by-step explanation:
We find determinant for the given matrix and set it equal to -1
To find determinant we apply formula


|A| = x^2 - 2x
Now we set the determinant = -1

Add 1 on both sides

Now factor it
(x-1)(x-1) = 0
Set each factor =0 and solve for x
x- 1=0 so x=1
me need slope and y intercept to get it in y=mx+b form (slope intercept)
Slope is the
difference in y / differences in x
differences in y = 6.5 -3 = 3.5
difference in x = 2 - 1 = 1
so slope is 3.5/1 or just 3.5
(now you can see the answer is c but lets check it by getting the y intercept too)
y intercept
this is when x is 0
the lowest x we see is 1 so if I go bacl to 0 in x the y must for back 3.5
3-3.5 is -0.5
so equation is y=3.5x -0.5 so the closest is c
Is there a picture to see from ?
