Answer:
y= -3x-12
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
Given that the slope is -3, m= -3.
Substitute the value of m into the equation.
y= -3x +c
Now, substitute the given coordinates into the equation.
When x= -5, y= 3,
3= -3(-5) +c
3= 15 +c
c= 3 -15
c= -12
Hence, the equation of the line is y= -3x-12

Answer:
y = 4x -16
Step-by-step explanation:
y+8= 4(x-2)
y+8=4x-8
y= 4x - 16
You want to find the measure of angle x. Rearrange the given 8 cos x+3=0 as <span>8 cos x= -3, or cos x = -3 / 8, or cos x = -0.375.
Use the arccos function (inverse cosine) to find the value of x in radians and in degrees.
Since the cosine function is negative only in Quadrants II and III, focus on the following possible ranges: Quadrant II: 90 < x < 180 and
Quadrant III: 180 < x < 270.
Example: using my calculator to obtain the inverse cosine of -0.375, I got x = 1.96 radians. Convert this into degrees if desired. Draw a ray showing this angle. Reflect this ray across the horiz. axis to obtain the angle in Q III.</span>
