Y intercept <br> x intercept<br> and the slope
masha68 [24]

Answer:

y-intercept = (0, - 3)

x-intercept = (-6, 0)

slope = - 1/2

Step-by-step explanation:

The y intercept is the value of y when the x = 0. By looking at the graph, we can tell that when x = 0, y = - 3. Likewise for the x-intercept.

We can use the slope formula to determine the slope.

m = y2 - y1/ x2 - x1

You can choose any 2 points on the line and substitute in the formula. I chose the y and x intercepts for easier calculations.

m = - 3 - 0/ 0 - (- 6)

m = - 3/ 6

m = - 1/2

What is the angle of elevation of the sun when a 49-ft mast casts a 22 ft shadow?
11Alexandr11 [23.1K]

Answer:

\theta=65.82^{\circ}

Step-by-step explanation:

Given that,

Perpendicular = 49 ft

Base = 22 ft

We need to find the angle of elevation of the sun. It can be calculated using trigonometry as follows :

\tan\theta=\dfrac{P}{B}\\\\\tan\theta=\dfrac{49}{22}\\\\\theta=65.82^{\circ}

So, the required angle of elevation is 65.82^{\circ}.
