2. Sabendo que uma reta tem coeficiente angular m = -2 e que ela passwa pelo ponto D ( -3 , - 1 ),
Determine a equação da reta.

3. Dado o ponto A ( -2 , 3 ) , calcule as coordenadas do ponto B ( 3k , k+1 ) de modo que o coeficiente
angular da reta AB seja m = 1/2

Translation of the problem here: 2. Knowing that a line has slope m = -2 and that it passes through point D (-3, - 1), Determine the equation of the line. 3. Given point A (-2, 3), calculate the coordinates of point B (3k, k + 1) so that the coefficient angle of the line AB is m = 1/2

We get the graph when the slope of the line=-2

Nós obtemos o gráficoquando a inclinação da reta = -2
