Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
In which m is the slope, and b is the y-intercept(y when x = 0).
Perpendicular lines
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to the line y=x−285.
This line has slope 1, so the line we want to find the equation has slope
Then
Passes through (7, 0)
This means that when . So
So
Find the value of k given that the line through (k, 2)
This means that when . So
The value of k is k = 5.
