Question

Ecuación de la recta y su pendiente (9,8) (-3,2) porfis

Answer 1

Respuesta:

[tex]y = mx + n[/tex]

[tex]m = \frac{2 - 8}{ - 3 - 9} = \frac{ - 6}{ - 12} = \frac{1}{2} [/tex]

[tex]8 = 9 \times \frac{1}{2} + n \\ 8 = \frac{9}{2} + n \\ 8 - \frac{9}{2} = n \\ \frac{16}{2} - \frac{9}{2} = n \\ \frac{7}{2} = n[/tex]

[tex]y = \frac{1}{2} x + \frac{7}{2} [/tex]
