Which equation represents the line that passes through points B and C on the graph?
Digiron [165]

Answer:

Therefore, the equation represents the line that passes through points B and C on the graph will be:

                                             y=-2x-6

Step-by-step explanation:

From the diagram, it is clear that

  • the point B is (-4, 2)
  • the point C is (-2, -2)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-4,\:2\right),\:\left(x_2,\:y_2\right)=\left(-2,\:-2\right)

m=\frac{-2-2}{-2-\left(-4\right)}

m=-2

Substituting m = -2 and \left(x_1,\:y_1\right)=\left(-4,\:2\right) in the point slope form

y-y_1=m\left(x-x_1\right)

Thus the equation of line becomes

y-2=-2\left(x-\left(-4\right)\right)

y-2=-2\left(x+4\right)

y-2=-2x-8

y=-2x-6

Therefore, the equation represents the line that passes through points B and C on the graph will be:

                                             y=-2x-6
