Find an equation in point-slope form for the line having the slope m= - 4 and containing the point (4,5).
1 answer:
<h2>Answer: y - 5 = - 4 (x - 4)</h2>
Step-by-step explanation:
The point-slope form of a line is (y - y₁) = m(x - x₁)
Since we know the slope (m) is -4
And the point ( x₁, y₁ ) is (4, 5)
Then we can just plug these into the equation above:
⇒ y - 5 = - 4 (x - 4)
<em>I often use Desmos to check my answer. As seen below, the equation does pass through the point (4, 5).</em>

Combining like terms:
Just divide the number of parts made by the number of hours to get parts per hour. 15 minutes is 1/4 of an hour, so we divide 360 by 0.25 hours:
