Answer:
y = -4x + 14
Step-by-step explanation:
using the slope intercept form of a line
y = mx + c
Given points
- 1, 10
- 3, 2
slope (m) =
taking one point as for filling x and y and finding the y intercept (c)
y =mx + c
10 = (-4) × 1 + c
10 + 4 = c
14 = c
therefore the equation is
y = -4x + 14
Answer:
r =
r = 17.2 cm
Step-by-step explanation:
∵ The area of the circle A = πr²
∴ r² = A/π
∴ r = √(A/π)
∵ A = 54 cm²
∵ π = 22/7
∴ r = √(54/(22/7)) = √(54×7/22) = 17.2 cm
