Question and choices are in the photo please explain the answer

A

Step-by-step explanation:

For this question, you want to use y=mx+c, where m is the gradient and c is the y-intercept.

We can see the line passes through (-4, 6) and (-1,2), so we can use those points to work out the gradient.

The formula for gradient is m=.  By substituting the values above, you get m=, which becomes or .

Since we can't exactly determine the y-intercept from the photo, we can sub it in to what we already know to work it out.

Using the point (-4, 6), y=x+c can be written as 6=(-4)+c.

This can be expanded to 6=+c or 6=+c.

Subtracting from both sides gives c=.

Putting this all back in the question, we get y= x+, or A.

**This question involves writing linear equations, which you may want to revise. I'm always happy to help!

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
