If x=3 and y=5 then you just substitute.
6(5)/3
30/3
=10
10 is your answer.
X must be increased by 6 to get its value to be 0. Then the corresponding change in y will be (-2/3)*6 = -4. That value added to -5 makes it -9.
The y-intercept will be -9.

Answer:
u=54
Step-by-step explanation:
VX is middle line of triangle, so
VX=ZY/2.....(1)
We know that
Zy=u
Vx=u-27
Put that in (1) we have:
u-27=u/2
2u-54=u
2u-u=54
u=54
Answer:
Yes
Step-by-step explanation:
The formula for area of a triangle is A = (1/2)bh,
For the first triangle we can leave it in general terms, so it's area is
A = (1/2)bh, depending on what b and h are, but it doesn't matter here...
The second triangle has base that is twice the other triangles base. Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is
A = (1/2)(2b)h, which simplifies to
A = bh
Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional
