Answer:
<h2>y - 4 = -2(x - 6) or y - 2 = -2(x - 7)</h2>Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
The formula of a slope:
We have the points (6, 4) and (7, 2). Substitute:
Using the first point
Using the second point
Answer:
B
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 4, - 1)
m = =
=
Use either of the 2 points for (a, b)
Using (a, b) = (- 4, - 1), then
y - (- 1) = ( x - (- 4)), that is
y + 1 = (x + 4)
Answer:
See the picture attached
Step-by-step explanation:
The graph of y = -|x + 3| is the graph of y = |x| translated three units to the left, since a "+ 3" is applied to the variable x, and next reflected respect the x-axis, since a "-1" multiply the function.
