Question

3x+6y=90 what is y intercept and x intercept? how are you getting the answer? I am having trouble with this...

Answer 1

first put x=0 and u get 3(0) + 6y = 90
or 6y = 90
or y = 90/6 = 15 this is the y intercept

similarly put y=0 and calculate to get the x-intercept...

Answer 2

for y intercept put x=0
and for x intercept put y=0

and ur answers are 15 and 30 respectively

Answer 3

for y=0
3x + 6(0) = 90
3x = 90
x= 90/3
x= 30 this is your x intercept


u can use this for all other questions
for y intercept put x=0 and calculate
for x intercept put y=0 and calculate

Answer 4

I think I understand it a little better,
now thank you
