Answer:
Step-by-step explanation:
3.
ACE, BCE, DCE, FCE
4. BCF
supplementry means to form an 180 angle(straight line) which bcf and acf form.
5. You have to do it
6. Right
7.
Using the same rule as in 4. We can say bce and ace are supplementar.
Slope itnercept is y=mx+b
ok, let's start with point slope form
y-y1=m(x-x1)
a point on the line is (x1,y1) and the slope is m
so given point (-3,4) and slope -3/4
y-4=-3/4(x-(-3))
y-4=-3/4(x+3)
distribute to solve for y
y-4=(-3/4)x-9/4
add 4 to both sides
y=(-3/4)x-9/4+4
y=(-3/4)x-9/4+16/4
y=(-3/4)x+7/4
-45.6 is the answer if you evaluate
Subtract 3x from both sides:
-6y = -3x + 6
divide both sides by -6 to get y by itself:
y = 1/2x - 1
function notation is rewriting y as a function:
f(x) = 1/2x -1
