Question

observe a equaçao polinominal y+ 2x - 5. assinale a alternativa , cujo grafico melhor representa a reta dessa equaçao

Answer 1

$y=2x-5 \\ \\ se ~~ y=0 \\ \\ 2x-5=0 \\ 2x=5 \\ x= \frac{5}{2} =2,5 \\ \\ ponto~~( 2,5;0)~~corta~~eixo~~x \\ \\ se~~x=0 \\ \\ y=2(0)-5 \\ y=-5 \\ \\ ponto~~(0,-5)~corta~~eixo~~y \\ \\ Ser\'a~~letra~~D~~\'unico~~que~~corta~~y~~em~~-5$
