1) Triangular pyramid
2) A cone
3) I don't have the picture of the figure so I don't know
The slope intercept form of the equation of a line is given as:
y = mx + c
where m = the slope of the line
c = the y - intercept of the line
1) Two line are parallel if they have the same slope
That is:

2) Two equations are perpendicular if the slope of one is the negative inverse of the other.

3) Two equations are coincidental if they have the same slope and the same y intercept
Answer:
a i think but im not sure
Step-by-step explanation:
Answer:
RS = 5
Step-by-step explanation:
Since R is between Q and S , then
QS = QR + RS , that is
6x - 3 = 3x - 2 + 2x + 1
6x - 3 = 5x - 1 ( subtract 5x from both sides )
x - 3 = - 1 ( add 3 to both sides )
x = 2
Then
RS = 2x + 1 = 2(2) + 1 = 4 + 1 = 5
