Question

d=√(x2-x1)²+(y2-y1)² en x1= -3, x2= 4, y1= -1, y2= 5​

Answer 1

Respuesta:

Explicación paso a paso:

y1 = 0 and y2 = 18

x1 = 4 and x2 = 8

slope = (y2 - y1)/(x2 - x1) = (18 - 0)/(8 - 4) = 18/4 = 9/2

The eqn of line with slope 9/2 and passing through (4,0) is

y - 0 = 9/2(x - 4)

y = (9/2)x - 18

f(x) = 9/2(x - 4)
