Answer:
9.42
Step-by-step explanation:
We have two points so we can find the gradient using y1-y2/x1-x2
gradient = 21-27/2-8
= 1
we know the form for any linear equation is y = mx + c
we have m and a point so we can substitute in point (2,21) to find c
21 = 1 x 2 + c
c = 19
therefore, the equation is y = x + 19
The answer is 6,889. Squared just means the number times itself. In this case, it's 83 x 83. :)
