Identify which equation represents a line perpendicular to the given equation 2x+5y=25
1 answer:
Answer:
y = 5/2x + 5
y = 5/2x - 9.5
Step-by-step explanation:
We need to solve for the y in the expresion of 2x + 5y = 25

now we re-arrenge the factors in the form y = ax + b
y = -2/5x + 5
we reverse "a"
y = 5/2 + a
And now, we use a point in the other formula to solve for a:
original line:
y = 5 - 2/5x
X = 0 then Y = 5
now we solve for the general equation of the perpendicular equation:


If we use a different point we get a different formula:
original line:
y = 5 - 2/5x
X = 5 then Y = 3
