What is the slope of -y=-x+6
Katarina [22]

<u>Answer:</u>

  • m = 1
  • b = -6

<u>Step-by-step explanation:</u>

We know that:

  • -y = -x + 6
  • y = mx + b

First, we need to change the 'y' sign.

  • => -y = -x + 6
  • => y = x - 6

Now, let's compare both of the equations to find slope.

  • => (y = x - 6) = (y = mx + b)

We can see that the slope is 1 and the y-intercept is -6.

<u>Conclusion:</u>

Therefore:

  • m = 1
  • b = -6

Hoped this helped.

Please help me answer all parts of question 3 in the photo.
Nookie1986 [14]
(i.) CA = πrl
CA = π (5*13)
CA = 65π

(ii.) TA = πrl + πr^2
TA = 65π + π (5^2)
TA = 65π + 25π
TA = 90π

(iii.) To get the height of the cone, you have to use the Pythagorean theorem. Plug in the radius for a and the slant height for c.

a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169 Height = 12
b^2 = 144
b = 12

(iv.) v = (1/3)πr^2h
v = (1/3)π(5^2)*12
v = (1/3)π(25*12)
v = (1/3)π*300
v = 100π
