Answer 1

ANSWER

The y-intercept if Function A is higher on the y-axis.

EXPLANATION

Function A is a constant where the slope is 0 and the y-intercept is 4.

Given two points for function B we can find the equation of the line. The formula for the slope of a line that passes through points (x1, y1) and (x2, y2) is:

$m=\frac{y_1-y_2}{x_1-x_2}$

For this line the slope is:

$m=\frac{2-2}{3-10}=\frac{0}{-7}=0$

This means that for function B the slope is also 0 and therefore the function is constant function where the y-intercept is 2.

Hence the y-intercept of Function A is higher on the y-axis
