Answer:
The y-intercept of the line is 32
Step -by -step explanation :
The general form of equation of a line that will pass through the three points is:
y=mx+c
where m is the gradient and c is the y-intercept
Now, find the gradient.
Take,
By substitution,
we now put the values of m, x and y into the general equation to find the c
Hence the y-intercept of the line is 32
I think the possible answer is Jalen used an ordered pair that is not on the line

Answer:
A(r) = √2 * r
A(r) Domain is R { r ; r > 0}
Step-by-step explanation:
Diagonals of a square intercept each other in a 90° angle. The four triangles resulting from diagonal interception are equal and are isosceles triangles, with hipotenuse a side of the square
Therefore we apply Pythagoras theorem
Let x be side of square, and r radius of the circle, ( diagonals touch the circle) then
x² = r² + r²
x² = 2r²
x = √2 * r
Now Aea of square is :
A = L² where L is square side
A(r) = √2 * r
Domain of A(r) = R { r, r > 0}
