Answer:
y=7
Step-by-step explanation:
To calculate the standard equation of a line given two points, you need to calculate the slope and the y intercept.
The slope is the change in y variables over the change in x variables between two points.
(7-7)/(4-0)
that gives you a slope of 0, ie the line is horizontal. That means that the y value is going to be constant while the x value changes, so you can write the equation as y= y value in any point, so y=7.
