Final answer:
The equation of the line with a slope of zero and passing through the point (3, -7) is y = -7. This represents a horizontal line, which is the same in both slope-intercept form and standard form.
Step-by-step explanation:
The student is asking how to write an equation in both standard form and slope-intercept form given the slope (m = 0) and a point (3, -7). In the slope-intercept form, the equation of a line is given by y = mx + b, where m is the slope and b is the y-intercept. Since the slope (m) is 0, the line is perfectly horizontal and the equation simply becomes y = b. Since the line passes through the point (3, -7), the value of y is -7 for all values of x, so the equation in slope-intercept form is y = -7.
For the standard form of the equation, which is Ax + By = C, with A, B, and C being integers, the same horizontal line can be expressed as 0x + y = -7 or simply y = -7 after removing the zero term. Therefore, the standard form of the equation is also y = -7.
