Answer:
M(0, 7)
Step-by-step explanation:
The attachment shows a plot of the segment and the X and Y coordinates of the midpoint. These can be found on a graph by counting squares and finding the point that is half the distance horizontally (X) and vertically (Y) between the given points.
The coordinates of the midpoint (M) are the x-coordinate of X (0) and the y-coordinate of Y (7).
M(0, 7) is the midpoint of AB

Answer:
y = 4x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = E(4, 4) and (x₂, y₂ ) = F(2, - 4)
m = =
= 4 , then
y = 4x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (4, 4), then
4 = 16 + c ⇒ c = 4 - 16 = - 12
y = 4x - 12 ← equation of line
