1. Write in y=mx+b Form 8x+2y=18. 8x+2y=18 8 x + 2 y = 18. The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept.

Answer:

y = -7

Step-by-step explanation:

distribute a 2 across each term in the second equation to get:

14x - 2y = 70  

now add it to the first equation to get:

22x = 88

x = 4

now substitute 4 for 'x' in either equation to get value of 'y':

7(4) - y = 35

28 - y = 35

-y = 7

y = -7

Check:

8(4) + 2(-7) = 18

32 - 14 = 18

18 = 18
