99 points for the correct answer! if not i will report you! find the slope of the line lm on the graph. a) -2 b) -1 c) -1/2 d) 1/2

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?
