Graph the equation on the coordinate plane.y=2x-1
Yakvenalex [24]

This equation is written in slope intercept form

Remember that the slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

In this case:

slope (m) is 2

y-intercept (b) is (0, - 1)

To plot this on a coordinate plane plot the y-intercept (0, -1).

To graph the rest of the line you can use what you know about the slope. Rise up two units and over to the right one unit from the y-intercept. You should arrive at the point (1, 1)

Then, again from the y-intercept, go down two units and to the left one unit. You should arrive at the point (-1, -3)

Now draw a straight line through the y-intercept and the other two points you just found

The image of the graph is shown below

Hope this helped!

Calculate the angle of depression, x, if the boat is 850 ft. away from the lighthouse and the lighthouse is 250 ft. high. Round
trapecia [35]

Firstly , we can draw diagram

we can see that

adjacent = 850

opposite =250

so, we can use tan formula

tan(x)=\frac{250}{850}

x=tan^{-1}(\frac{250}{850})

16.38

x=16.38

so,

angle of depression is 16.38 degree........Answer
