Answer:
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)
Below
● -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
