Question 199526
A) solve 5x + 6y = 18 for y
6y = -5x + 18
y = (-5/6)x + (18/6)
y = (-5/6)x + 3
.
B) When graphed this equation would be a line. By examining your answer to part a, what is the slope and y-intercept of this line?
slope= -5/6
y-intercept= 3 or at (0,3)
.
C) Using your answer from part a, find the corresponding value of y when x = 12
Plug into:
y = (-5/6)x + 3
y = (-5/6)12 + 3
y = (-5)2 + 3
y = -10 + 3
y = -7
