y = 7
x = 4 is a vertical line parallel to the y- axis passing through all points with an x- coordinate of 4
A line perpendicular to x = 4 will be a horizontal line parallel to the x- axis with equation y = c where c is the value of the y- coordinate the line passes through.
line passes through (5 , 7) with y- coordinate 7
The equation is therefore y = 7
Answer:if you looked at hem like they were rows, in the first row the third one would be an expression. In the second row, the second one would be an expression. This is becuase they both have an equal sign.
