4x+8y=16
Move the 4x to the other side to put it into slope intercept form.
8y=-4x+16
Then divide by 8.
Y=-1/2x+2
The slope is -1/2 and the Y intercept is 2.

Answer:
x = (-9)
Step-by-step explanation:
From the diagram, we see that the triangle is an isosceles triangle. Since it is an isosceles triangle we know that the angles at the base of an isosceles triangle are equal to each other, so the angles that is not marked will be equal to m∠2. Since now we know that, we can make the following equation...
m∠2 + m∠2 + 84 = 180
Now we solve it and get...
2(m∠2) = 180 - 84
2(m∠2) = 96
m∠2 = 48
Now we substitute m∠2 with x + 57, and get...
m∠2 = 48
x + 57 = 48
x = 48 - 57
x = (-9)

Answer:
x = 12
Step-by-step explanation:
Looking at the diagram, we can deduct that the appropriate formula to use is form power of a point, specifically when two secants intersect outside of a circle. Using this, you get the equation:
(x + 5 + 7)(7) = (x + 1 + 8)(8)
And, you can simplify and solve:
(x + 12)(7) = (x + 9)(8)
7x + 84 = 8x + 72
84 = x + 72
x = 12
