Question

Choose the graph which matches the following system of equations.
x + 2y = 5
3x – 2y = –9

Answer 1

rearrange each equation to y = mx + b form
where m = slope and b = intercept on y-axis
and compare them to the graphs

Answer 2

can you do the rearranging?

Answer 3

Would the first equation be y= -1/2x-5/2?

Answer 4

or positive 5/2?

Answer 5

yes + 5/2

Answer 6

then would the second equation be y=3/2x+ 9/2

Answer 7

so intersect on y-axis will be at 2.5

Answer 8

yes

Answer 9

correct for 2nd equation

Answer 10

so since the y axis for the first equation is 2.5 is the answer choice three (graph4)

Answer 11

yes

Answer 12

awesome, thank you so much!
