Answer:
y +4 = (1/5)(x +5)
Step-by-step explanation:
The point-slope form of the equation of a line is useful when you have a given point and slope.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Filling in the given values, this is ...
y +4 = 1/5(x +5)
Answer:
slope = 
Step-by-step explanation:
Calculate slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = 
= 
= 
=
Answer:
64k^2 - 16k +1
Step-by-step explanation:
We can rewrite this as
(-8k+1) ^2
We know that (a+b)^2 = a^2 +2ab +b^2
Let a = -8k and b = 1
(-8k+1) = (-8k)^2 +2*(-8k)(1) + 1^2
=64k^2 - 16k +1
