Question 92561
What is the equation of a line with a slope of -5 and containing the point (2,4):
:
use the point/slope formula: (y - y1) = m(x - x1)
:
In your problem m = -5, x1=2; y1=4, so substitute and you have:
y - 4 = -5(x - 2)
:
y - 4 = -5x -5(-2);multiplied what's inside the brackets,
:
y - 4 = -5x + 10; minus * minus = +
:
y = -5x +10 + 4; add 4 to both sides
:
y = -5x + 14, is the equation
