Answer:
y = - 
x + 3
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 )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 10, 17) and (x₂, y₂ ) = (5, - 4)
m = 
= 
= -
y = - x + c ← is the partial equation
to find c substitute either of the 2 points into the partial equation
using (5, - 4), then
- 4 = - 7 + c ⇒ c = - 4 + 7 = 3
y = - x + 3 ← in slope-intercept form
Answer:
11 inches
Step-by-step explanation:
We want to work out the radius of the cylinder in inches so we have to utilise the volume of a cylinder formula which is
Volume = π × r² × h
Where "r" is the radius and "h" is the height
→ First substitute the value into the formula
121 π = π × r² × 1
→ We can divide both sides by π to get rid of it
121 = r² × 1
→ We should divide both sides by 1 to isolate r²
121 = r²
→ Now, we can square root both sides to find the value of the radius
11 = r
→ So the radius of the cylinder is 11 inches
