Write the equation for a line that passes through the point (2,5) and a slope of m =10 in point slope form
2 answers:
Since we're given a point and a slope, we can write
the equation of this line using the point-slope formula.
The point-slope formula is shown at the top of the image below.
The given point, (2,5), represents (x1,y1).
Now plug in the information to get the equation below.
Now you can distribute the 10.
Then add 5 to both sides.
You will end up with the equation y = 10x - 15 as your answer.

Answer:
f(x) = -8(4)x
Step-by-step explanation:
The reflection of the point (x,y) across the x-axis is the point (x,-y).
Having said this, to reflect the function y=g(x) = 8(4x) over the x-axis, we just need to evaluate the equation in the point: (x,-y).
y = 8(4x) ⇒ -y = 8(4x) ⇒ y = -8(4x)
Then f(x) = -8(4x)
Attached you will find the graph of g(x) (blue) and f(x) (red),
