True
Step-by-step explanation:
If there is an equilateral triangle or just a triangle that the vertex and midpoint on the bottom segment line up, then a perpendicular bisector and altitude can be the same thing.
Answer:
y = -1/4x + 7
Step-by-step explanation:
Plug in the point and slope into y = mx + b, and solve for b:
y = mx + b
8 = -1/4(-4) + b
8 = 1 + b
7 = b
Plug in the slope and b into y = mx + b:
y = mx + b
y = -1/4x + 7
So, the equation of the line is y = -1/4x + 7
