anonymous · Answer

Wait, is the answer 10?

anonymous · Answer

5x + 2y = 20 

Subtract 5x from both sides 

5x - 5x + 2y = 20 - 5x 

Simplify 

2y = -5x + 20 

Divide both sides by 2 

2y / 2 = (-5x + 20) / 2 

Simplify 

y = -2.5x + 10  

^ is that why it is -10?

ok let me show you the work y-intercept = 20/-2=10/-1= -10.00000
