GIVING BRAINIEST TO SOMEONE WHO ANSWERS IN THE NEST 10 MIN!!!!!
Examine the system of equations.


t + f = 42,


2t + 4f = 100


Graph the first equation with t on the horizontal axis. Use the points (0, 42) and (42, 0).


Which describes how to graph the other equation in the system?

Graph (0, 25) and (25, 0).

Graph (0, 25) and (50, 0).

Graph (0, 50) and (50, 0).

Answer:

Graph (0, 25) and (50, 0)

Step-by-step explanation:

Intercept form of an equation for a line is ...

  • x/(x-intercept) + y/(y-intercept) = 1

Dividing each equation by the constant on the right can put it into this form.

First equation:

  • t/42 + f/42 = 1

Second equation:

  • t/50 + f/25 = 1

This tells you the second equation can be graphed using the points ...

... (50, 0) and (0, 25) . . . . . matches the second selection
