Out can affect of a line of best fit calculated using the least squares method.
a-the slope
b-the y intercept
c-both a& b
d-none of the above

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
