Question

ACHE A INCLINAÇÃO ( COEFICIENTE ANGULAR) E O INTERCEPTO VERTICAL ( COEFICIENTE LINEAR) DA RETA CUJA EQUAÇÃO É 2 Y + 5X-8=0

Answer 1

$y=ax+b$

a = coeficiente angular (acompanha x)
b = coeficiente linear

$2y+5x-8=0$

isolando y
$2y+5x-8=0\\\\2y-8=0-5x\\\\2y-8=-5x\\\\2y=-5x+8\\\\y= \frac{-5x+8}{2} \\\\y= \frac{-5x}{2} + \frac{8}{2} \\\\\boxed{y= \frac{-5x}{2} +4}$

a= -5/2 (coeficiente angular)

b = 4 (coeficiente linear)
