Question

Find the equation of the line. Use exact numbers. y =__ x +__​

Answer 1

EXPLAIN:

Ex: the line is: y = ax + b

The line go through 2 points ( 0 ; -5 ) and ( 5 ; 0 )

So:
`\left \{ {{0=5a+b} \atop {-5=0a+b}} \right. =>\left \{ {{b=-5a} \atop {b=-5}} \right. =>\left \{ {{a=1} \atop {b=-5}} \right.`

The line: y = x - 5 = (1)x + (-5)

ANSWER: y = (1)x + (-5)

ok done. Thank to me :>
