Answer:
the slope of the line is -11/7 and the y-intercept is 8.
Explanation:
First, we'll add 11x + 7y to both sides:
-11x - 7y + 11x + 7y = -56 + 11x + 7y
0 = -56 + 11x + 7y
Then, we'll add 56 to both sides:
0 + 56 = -56 + 11x + 7y + 56
56 = 11x + 7y
Finally, we'll divide both sides by 7:
56/7 = (11x + 7y)/7
8 = (11x + 7y)/7
Now we have the equation in slope-intercept form:
y = -(11/7)x + 8
So in this case, the slope of the line is -11/7 and the y-intercept is 8.
