Please help me with this one please, I've been having trouble figuring this one out.

Answer:

y = - 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (2, - 3)

m = $\frac{-3-5}{2+2}$ = $\frac{-8}{4}$ = - 2

The line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = - 2x - 1 ← equation of line

The formula for a cylinder's surface area is : $2\pi rh+2\pi { r }^{ 2 }$ in this question, h=x.

Let's plug the values in the formula

$2\pi rh+2\pi { r }^{ 2 }\\ \\ 2\cdot \pi \cdot 6\cdot 8+2\cdot \pi \cdot { 6 }^{ 2 }=2\cdot 48\cdot \pi +2\cdot 36\cdot \pi =96\pi +72\pi =168\pi \quad \\ \\ 168\pi \quad square\quad units\\ Answer\quad is\quad A$
