Answer:
7/6
Step-by-step explanation:
the original line has a slope of -6/7, so the line perpendicular is 7/6. we swap the numerator and denominator, and if the starting slope is positive, the perpendicular slope would be negative, and the other way around.
Answer:
The equation to express this situation is <em>y</em> = 15<em>x</em> + 50.
Step-by-step explanation:
Initially, the temperature of a pot of water is 50⁰, i.e. at after <em>x</em> = 0 minutes the temperature was, <em>y</em> = 50⁰.
And the temperature rises 15⁰ per minute.
So, after <em>x</em>₁ = 5 minutes, the temperature was, <em>y</em>₁ = 125⁰.
And similarly after <em>x</em>₂ = 10 minutes, the temperature was, <em>y</em>₂ = 200⁰.
Compute the equation to express this situation as follows:

Thus, the equation to express this situation is <em>y</em> = 15<em>x</em> + 50.
