Answer 1

start by finding the x-intercept and y-intercept

2x + 5y = 10

when x = 0, what does y equal?

Answer 2

5?

Answer 3

nope.

plug in x = 0

Answer 4

if x = 0, what does 2x equal?

Answer 5

0

Answer 6

good

so

2x + 5y = 10

becomes

5y = 10

so what does y equal?

Answer 7

2

Answer 8

good, so our y-intercept is 2.

now we let y = 0 to find the x-intercept

2x + 5y = 10

when y = 0, what does x equal?

Answer 9

5

Answer 10

good!

so our graph crosses the x-axis at 5 and the y-axis at 2.

now look at the graphs and tell me which one matches

Answer 11

line b?

Answer 12

yup! great work ~

Answer 13

thanks for helping me
