To find y-intercepts, you substitute in 0 for X
2y-5x=16
2y-5(0)=16
2y-0=16
2y=16
Y=8
So the y-intercept is (0,8)
Answer: -8 and -4
This is something you do through trial and error. Making a list or a table like shown below might help.
Answer: 186%
To get this simply divide 93 into 50 (you will get 1.86 which you can convert to the percentage 186%). An even easier way is to multiply 93 by two (186) since 50% times 2 is 100%. Hope this helps!
Slope = 0 do answer is y = 1
