Write an equation of a line that passes through the point (-1,-4) and has a slope of 2.

STatiana [176]

Answer:

Y = 2x + 7

Step-by-step explanation:

We know that the slope is 2 so it is 2x

To get the y - intercept of 7 we draw the graph.

if we start at point (-1,-4) and use a slope of 2 the point that lands on the y axis is the y intercept. In this case the y intercept is 7.

beks73 [17]

The image of the given scenario is attached below.

A right angled triangle is formed, with one angle equal to 27 degrees. The perpendicular side is 155 and we are to find the length of guy wire which makes the hypotenuse of the right angled triangle.

Using the formula of sine, we can write:

$sin(27)= \frac{155}{x} \\ \\ 
x= \frac{155}{sin(27)} \\ \\ 
x=341$

Rounding to nearest whole number, the length of the guy wire that must be attached is 341 feet.
