What is the equation of aline that passes through the point (4,-8) and has a slope of -1/2?
viktelen [127]

Answer:

The equation of the line will be:

y=-\frac{1}{2}x-6

Step-by-step explanation:

Given

  • slope = m = -1/2
  • point (4, -8)

Point slope form:

y-y_1=m\left(x-x_1\right)

substituting the values m = -1/2 and the point (4,-8)

y-\left(-8\right)=\frac{-1}{2}\left(x-4\right)

y+8=\frac{-1}{2}\left(x-4\right)

subtract 8 from both sides

y+8-8=\frac{-1}{2}\left(x-4\right)-8

y=-\frac{1}{2}x-6

Therefore, the equation of the line will be:

y=-\frac{1}{2}x-6

Please the question below 55
Nataliya [291]

Answer:

The value of x is 17.32

Step-by-step explanation:

It can clearly be seen that the triangle is a right-angled triangle.

In the triangle, according to reference angle 13 degree,

Base = 30

Perpendicular = x

We can use trigonometric ratios for finding the value of x

As tangent includes both perpendicular and base, we can use this.

So,

tan\ 30 = \frac{perpendicular}{base}\\tan\ 30 = \frac{x}{30}\\0.5773 = \frac{x}{30}\\x = 0.5773*30\\x = 17.319

Rounding off to nearest hundredth

x = 17.32

Hence,

The value of x is 17.32
