Write the equation of the line that has an undefined slope and passes through the point (4, 7).
y = 4
x = 4
y = 7
x = 7

B.

Step-by-step explanation:

We have been given coordinate of a point (4,7). We are asked to find the equation of the line that has an undefined slope and passes through the given point.

We know that slope of a vertical line is undefined. So the vertical line passing through point (4,7) will have an undefined slope.

The slope of line will be undefined when x-coordinates of all points on the line are equal.

Since the line will have same x-coordinates for all y-coordinates, therefore, option B is the correct choice.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
