Y = 1.2x + -1.3
y = -0.8x + -2.5

how do you solve this with substitution??

x= -0.6  and   y = -2.02

Step-by-step explanation:  

y = 1.2x + -1.3 ... (Equ 1)  

y = -0.8x + -2.5 ...(Equ 2)    

In (Equ 2), Substitute 1.2x + -1.3 for y      

y = -0.8x - 2.5        

1.2x + -1.3 = -0.8x + -2.5      

1.2x + 0.8x = -2.5 + 1.3        

2x = -1.2      

x = -1.2/2

x= -0.6  

To find y, substitute -0.6 for in (Equ 1)

y = 1.2x + -1.3

y = 1.2(-0.6) - 1.3

y = -0.72 - 1.3

y = -2.02

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry
