Answer:
Step-by-step explanation:
First, determine the slope of the radius by the equation,
m = (y₂ - y₁)/ (x₂ - x₁)
Substituting the known values,
m = (1 - -2)/(8 - 4) = 3/4
If the unknown line is perpendicular to this, the slope should be the negative reciprocal which is equal to -4/3. Using the point-slope form to determine the equation,
y - y₁ = m(x - x₁)
Substituting the known values,
y - -2 = (-4/3)(x - 4)
Simplifying,
y + 2 = (-4/3)(x - 4)
3y + 6 = -4x + 16
<em> Answer: 4x + 3y = 10</em>
Answer:
The temperature at 10 am in the morning was 1 degree below zero.
First, we know at 8 am that the temperature was 3 degrees below zero so that number is -3 and it’s our starting number.
Next, it says an hour later the temperature has gone up 6 degrees so we have -3 + 6 and we get a sum of positive 3.
Finally, at 9 am the temperature dropped again but this time 4 degrees so 3 - 4 = -1
The temperature at 10 am in the morning was 1 degree below zero.
