Para encontrar la recta primero hay que encontrar la pendiente que es m.
Que sería de esta forma: m = y2-y1/x2-x1 que es igual m = 2-1/5-(-4). Entonces la pendiente m= 1/9. habiendo hecho esto haces la ecuación de la recta, que es la siguiente: y=mx+b. Entonces sería
2=1/9(5)+b y resuelve para b.
2=1/9(5)+b
2=5.1/9+b
2=5/9+b
2=5+9b/9
9.2=9b+5
18=9b+5
18+(5)=(9b+5)+(-5)
13=9b+5-5
13=9b
9b/9=13/9
b=13/9
Habiendo encontrado el valor de b, la ecuación de la recta que pasa por los puntos (-4,1) (5,2) es la siguiente: y=mx+b es igual a y=1/9x+13/9...
