Question

What is the slope of the line: y=-1/2x+3?

a. m=-1/2
b. m=3
c. m=2
d. m=-3


also,

Use the formulas for a cone:
r=3
l=4
LSA=?

a. 24π
b. 12π
c. 36π
d. 28π

I'm having a hard time figuring out the two. if you could please explain how I can solve this it would be great. thank you!

Answer 1

What is the slope of the line: y=-1/2x+3?

y = mx + b where m = slope

so y=-1/2 x+3 ; m = -1/2

answer:

a. m= -1/2

-------

Use the formulas for a cone:

r=3

l=4

LSA=?

LSA = πrl

LSA = π*3*4 = 12π

answer

b. 12π
