Find the y-intercept of the rational function. a rational function is graphed in the first quadrant, and in the second, third and fourth quadrants are other pieces of the graph. the graph crosses the x axis at negative 10 and crosses the y axis at negative 2. (0, −10) (−10, 0) (0, −2) (−2, 0)

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
