Answer:

Any line with the slope of 4/3 would be perpendicular.

Step-by-step explanation:

To find this, first solve the equation for y.

3x + 4y = 7

4y = -3x + 7

y = -3/4x + 7/4

Perpendicular lines always have opposite and reciprocal slopes. Therefore, we flip the slope in the original equation (-3/4 becomes -4/3) and then we change the sign (-4/3 becomes 4/3)

Two consecutive vertices of a regular octagon are located at (1, 4) and (4,8). This octagon's perimeter is.....?

Answer:

40 units

Step-by-step explanation:

An octagon is a polygon with 8 sides. A regular octagon is an octagon in which all their sides and angles are equal to each other.

Since the vertices of a regular octagon are located at (1, 4) and (4,8), hence the length of the side is gotten using the formula for calculating the distance between two points $X(x_1,y_1)\ and\ Y (x_2,y_2)$ .
