Solve the systems of equations:
y=-3x+4
y=4x-10

x = 2

y = -2

(2,-2) in point form

x=2 and y=-2

Step-by-step explanation:

y+3x= 4(1)

y-4x= -10(2)

Subtract equation 2 from 1

y+3x= 4

-y-4x= -10

0+7x = 14

7x = 14

divide both sides by 7

7x = 14

7 7

x = 2

Substitute x=2 into equation 1

y = -3x + 4

y = -3(2) + 4

y = -6 + 4

y = -2

x = 2 and y = -2

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
