Y=4x²-7x+13
y-13=4(x²-(7/4)x)
y-13+4*(7/8)²=4(x²-2*(7/8)x+(7/8)²)
y-13+4*(7/8)²=4(x-(7/8))²
y-13+ 3.0625=4(x-0.875)²
y-9.9375=4(x-0.875)²
y=4(x-0.875)² +9.9375
Hello there!
The slopes of perpendicular lines are opposite reciprocals. It means we take the slope of the given line, flop it over and make it negative.
And then just plug in the points:
y-y1=m(x-x1)
y-3=-1/4x-(-5)
y-3=-1/4x+5
Hope this helps!

Answer:
As x increases, the rate of change of f(x) exceeds the rate of change of g(x).
Step-by-step explanation:
Answer:
y = -2x -8
Step-by-step explanation:
The equation for a line can be written in slope intercept form
y =mx+b where m is the slope and b is the y intercept
the slope is -2 and the y intercept is -8
y = -2x -8
