I've been having a lot of trouble with questions like this and was wondering if someone could help me

The table represents a linear function. what is the slope of the function? –6 –4 4 6

If a line is defined by the equation y = 5x + 2, what is the slope?

Find the equation of the ellipse with the following properties. the ellipse with foci at (0, 6) and (0, -6); y-intercepts (0, 8) and (0, -8).edit: the answer is x^2 over 28 + y^2 over 64 = 1
