Answer 1

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

Step-by-step 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=(y_1-y_2)/(x_1-x_2)`

For this line the slope is:

`m=(2-2)/(3-10)=(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
