Answer:
y = -4x + 58
Explanation:
Equation of line: y =mx + b
Here, m is the slope and b is the y-intercept.
Parallel lines have same slope.
y = -4x + 9
m = -4
Equation of the required line: y = -4x + b
The line passes through (15, -2). Substitute x and y values and find the value of 'b'.
-2 = -4*15 + b
-2 = -60 + b
-2 + 60 = b
b = 58
Equation of line:
y = -4x + 58
