What are the slope and y-intercept of the graph of the given equation?
2 answers:
Answer:
The slope is -4 and the y-intercept is 2.
Step-by-step explanation:
Given the equation of line
As the general equation of straight line is
where m is the slope of line and c is y-intercept
Compare given equation with above equation, we get
m=-4 and c=2
Hence, the slope is -4 and y-intercept is 2
Therefore, Option A is correct.

Answer:
C) 405.3 ft
Step-by-step explanation:
A triangle is a polygon with three angles and three sides. Types of triangle are scalene, isosceles, equilateral, right angled triangle.
Given a triangle with angles A, B, C and the corresponding sides directly opposite to the angles as a, b, c. The sine rule states that:
In the triangle formed by point C, ship B and ship A, we have ∠A = 82°, ∠B = 78°, c = AB = 140 ft. Hence:
∠A + ∠B + ∠C = 180° (sum of angles in a triangle)
82 + 78 + ∠C = 180
∠C + 160 = 180
∠C = 20°
Using sine rule:
a = distance from Ship B to the signal fire at point C
