Respuesta :

Answer:

y = -15x + 250

Step-by-step explanation:

Slope: I see two distinct points: (14, 40) and (10, 100).

Using the slope equation, I get: (100 - 40)/(10 - 14) = -15.

The slope is -15, so in a point-slope formula, it will go before the x.

Y-intercept: on the graph, when x = 0, y is 250. That goes after the x +.
