So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
Answer:
y= 30 x=15
set up your proportions for example 9/6 to y/20 and 9/6 to x/10 and then cross multiply
Answer:
B its 4 7/8 --------------
Look up on yt how to find those. They r pretty easy.
