I CAN HELP YOUUUUUUUUUUUUUUUUUU!!!!!!!!!!!!!!!!!!1
lets distribute 7(x+3)
so 7(x)+7(3)
7x+21 or b
yay :)
Alternate interior angles are congruent. So, angle 3 = angle 7.
We see that vertical angles are congruent. So, angle 3 also = angle 5.
Alternate exterior angles are congruent.
So, angle 3 also = angle 1.
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
y = -3/2x - 1/2
b = -1/2
To locate the y-intercept on the graph, find the point where the line crosses through the y-axis or the y-value when x = 0
I can't see the graph but hopefully this information helps you find the answer
The answer is that the sum of x and y should be less than c
