Note that when a point P(a, b) is reflected with respect to the y-axis, the y coordinate does not change, while a becomes -a.
So the reflection of a point P(a, b) with respect to the y-axis is the point P'(-a, b).
According to this, the projections of the points (2,3), (-4,-5), and (-2, 4) are the points the points (-2,3), (4,-5), and (2, 4).
Answer: A
Z (>/=) -17
start by subracting 26 then multiplying by 2
Answer:
Step-by-step explanation:
you do part a
Equation 1: 4x+y=2
Equation 2: 3x-3y=9
b
Divide equation 2 by 3
x-y=3
add y to both sides
x=3+y
Sbustitute this into equation 1
4(3+y)=2
12+4y+y=2
5y= -10
y= -2
Plug this into equation 1
4x-2=2
x=1
Part c.
Equation 1: 4x+y=2
Equation 2: 3x-3y=9
divide equation 2 by 3
x-y=3
add the two equations
(x-y)+(4x+y)=2+3
5x=5
x=1
Plug this into equation 1
4(1)+y=2
4+y=2
y= -2
For part a just create a table and graph it
