Final answer:
The equation of the line in slope-intercept form is y = 7.
Step-by-step explanation:
The equation of a line in slope-intercept form can be written as y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 0. Therefore, the equation of the line will be y = 0x + b, which simplifies to y = b. Since we are given the point (4,7), we can substitute these values into the equation to find the value of b. So, 7 = b. The equation of the line in slope-intercept form is y = 7.
