Answer:
y = 7
Step-by-step explanation:
A line with a slope of 0 is a horizontal line parallel to the x- axis.
The equation of a horizontal line is
y = c ( where c is the value of the y- coordinates the line passes through )
The line passes through (3 , 7) with y- coordinate of 7, hence
y = 7 ← is the equation of the line
Option D
A
he actually made a mistake in second step. Step 2 should be: 10y-2=18 and then 10y=18+2
we get 10y=20 /:10
y = 2
7 P.M.
Time at which the walk was begun = 4 p.m.
Finished after rotating the clock 90° i.e. = 3 hours
Thus,
The time at which the task finished = 4 p.m. + 3hours
= 7:00 PM
