Answer:

Step-by-step explanation:

<u>Intercepts of a Line</u>

The x-intercept of a given line is the point where the line crosses the x-axis and the y-intercept of a given line is the point where the line crosses the y-axis.

We are given the following line:

-12x + 18y = 108

To find the x-intercept, we set y=0 and solve for x:

-12x + 18*0 = 108

-12x = 108

x = 108 / (-12) = -9

The x-intercept is the point (-9,0)

To find the y-intercept, we set x=0 and solve for y:

-12*0 + 18y = 108

18y = 108

y = 108 / 18 = 6

The y-intercept is the point (0,6)

Answer:

Slope=− 1.083/1.083 =−0.542

x−intercept= 144/13 =11.07692

y−intercept= 144/24 =6.

Need help on this one
Furkat [3]
The trick here is to not use sin and cos at all.

The -13/15 is the x coordinate of a line from the origin to the unit circle (the line with angle theta). That happens to be the cos(theta).

The y coordinate is the sin(theta).

You can draw this as a triangle where x^2 + y^2 = 1.

So y = √(1 - (13/15)^2) ≈ 0.49889. But your exact answer should be:

sin(\theta) = \sqrt{1-(\frac{13}{15})^2} = \frac{2\sqrt{14}}{15}
