Graph -7x+5y=35. khan acadmy forms of linear equations question. pls show work (10 points)

Below

Step-by-step explanation:

● -7x + 5y = 35

Add 7x to both sides

● -7x +7x + 5y = 35+7x

● 5y = 7x + 35

Divide both sides by 5

● 5y/5 = (7x+35)/5

● y = 1.4x + 7

The graph of the function:

Step-by-step explanation:

-7x+5y=35

write the equation in the form : y=mx+b

5y=35+7x ( divide both sides by 5)

y=7/5 x +35/5

y=7/5 x +7

if y=0   then 7/5 x+7=0 ⇒7/5 x=-7 ⇒x=-35/7 ⇒x=-5

x=0 then y=7

two points  (0,7) and (-5,0)

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
