Take any two points to find the slope of a line. The slope will be equal to:
(y2-y1)/(x2-x1) and any two points will do...
I'll use (-2,4) and (0,0) :P so the slope is:
(0-4)/(0--2)=-4/2=-2, now we know the slope is -2 so:
y=-2x+b (now we know b=0, but I'll use another point anyway to solve for b)
Let's use (-2,4) again...
4=-2(-2)+b
4=4+b
b=0
So the line is:
y=-2x
hope this helped!
I think i’m may be ‘B’ i’m so sorry if i’m incorrect!!
Answer:
<u>Find the slope:</u>
<u>Use point-slope form and one of the points:</u>
- y - y₁ = m(x - x₁)
Answer: f(-7) = 0
For the factored form of f(x), if x = -7, then one of the factors will be equal to 0, since (-7 + 7) = 0. This will cause the entire y-value to be 0, because anything multiplied by 0 = 0.
Answer:
Might not be answer but.
Step-by-step explanation:
Parallel lines are coplanar lines (in the same plane) that never intersect (never cross each other). The slope of a line measures its steepness (or its angle from the horizontal). Lines that are parallel have the same steepness (or the same angle from the horizontal).
