Answer:
The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)
Step-by-step explanation:
we know that
When you reflect a point across the line y= x, the x-coordinate and y-coordinate change places.
so
The rule of the reflection of a point across the line y=x is
(x,y) -----> (y,x)
we have
Points p(1,2) and q(4,3)
Applying the rule of the reflection across the line y=x
p(1,2) ------> p'(2,1)
q(4,3) -----> q'(3,4)
therefore
The new coordinates of the points of the line segment are p'(2,1) and q'(3,4)
Answer:
a is true
Step-by-step explanation:
its because 7+(-7) =0 so a is correct
Answer:
A≈12.57
r Radius 2
Step-by-step explanation:
The lines have equal gradients;
m

Equation of line 2;
y=mx+c
y=

x+c
-15=

+c
c=-11
y=4/5x-11
<span>y = 3x - 7
3 = slope
-7 = y intercept
This line would cross the y intercept at -7, and go up by 3 (slope). </span>
