write the equation of the line with x-intercept (-7, 0) na d undefined slope.
a) y= -7
b) x= -7
c) y= -7x
d) x= 0
The answer is b.
This is because an undefined slope is m/0.
So, its just a vertical line. Since x=-7, that's the line.
To find the equation of a line with an undefined slope, you need to remember that an undefined slope indicates a vertical line. In this case, the x-intercept is given as (-7,0), which means the line passes through the point (-7, 0) and is parallel to the y-axis.
Since the line is vertical, it means that the x-coordinate remains constant along the entire line, while the y-coordinate can take any value. Therefore, the equation of the line is in the form x = constant.
In this case, the x-intercept is (-7,0), so the constant value for the x-coordinate is -7. Hence, the equation of the line is x = -7. Therefore, the answer is option b) x = -7.
