Answer:
Step-by-step explanation:
first find the slope
m = Δy/Δx = (-1 - (- 5)) / (4 - (-2)) = 4/6 = 2/3
Then plug either point into the equation
y - y₁ = m(x - x₁)
y + 1 = 2/3(x - 4)
which is equivalent to
y + 5 = 2/3(x + 2)
Answer:
E - 40°
Step-by-step explanation:
Angle O = 2 × y
{Angle at center is equal to twice the angle at circumference formed by the same arc}
O = 2 × 70°
O = 140°
x + 90° + 90° + O = 360°
{Sum of angles in a quadrilateral is equal to 360°}
x + 90° + 90° + 140° = 360°
x + 320° = 360°
x = 40°
Answer:4(3)/(5)
Step-by-step explanation:
it would have to be a, because using pythagorean theorem, we can find that a squared + b squared = c squared. substitute that for 1 + b squared = 4; b squared=3 b = square root of 3
