Answer:
-0.67
Explanation:
What is the slope of the line created by this equation? Round your answer out to the two nearest decimal places. 6x + 9y = 1
_____________________________________________
Slope intercept form solves for y:
y = mx + b when m = slope and b = y-intercept
First, solve for y:
6x + 9y = 1
subtract 6x from both sides:
6x + 9y - 6x = 1 - 6x
9y = 1 - 6x
divide both sides by 9:
9y/9 = (1 - 6x)/9
y = 1/9 - 6/9x
reduce right side:
y = 1/9 - 2/3x
rearrange right side:
y = - 2/3x + 1/9
Back to the equation: y = mx + b when m = slope and b = y-intercept
your slope is -2/3
in decimal form, rounded to two digits: -0.67
