Use the slope formula. after you find the slope put it in slope intercept form.
slope formula is
Slope intercept form is y=mx+b m=slope b=y intercept
Soup b; no
soup c; yes
soup d; no
soup e; yes
Answer:
C & E
Step-by-step explanation:
∠3 and ∠5 are alternate interior angles
∠2 and ∠8 are alternate interior angles
(x+b/2a)^2-(b^2-4ac)/2a=0
Step 2:
Re-write the expression:
(x+b/2a)^2=(b^2-4ac)/4a^2
Step 3:
get the square root of both sides:
x+b/2a=sqrt[(b^2-4ac)/4a^2]
Step 4:
Simplifying we get:
x+b/2a=sqrt[b^2-4ac]/2a
Step 5
Make x the subject:
x=-b/2a+/-sqrt[b^2-4ac]/2a
