Graph the function y = 4 . Then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Elodia [21]

Given equation is y=4.

Question says to graph the given equation y=4 then use the graph to find the missing x- or y-coordinates for the function to the nearest hundredth.

Equation y=4 has no "x" so that means line y=4 will be a horizontal line which passes through 4 on y-axis.

Since it is parallel to x-axis so that means there is no x-intercept.

y-intercept is (0,4) as the line crosses at 4 on y-axis.
