What is the equation for​
WARRIOR [948]

The equation of a line that is perpendicular to the given line is y = –4x – 16.

Solution:

The equation of a line given is y = 0.25x – 7

Slope of the given line(m_1) = 0.25

Let m_2 be the slope of the perpendicular line.

Passes through the point (–6, 8).

<em>If two lines are perpendicular then the product of the slopes equal to –1.</em>

\Rightarrow m_1 \cdot m_2=-1

\Rightarrow 0.25\cdot m_2=-1

\Rightarrow m_2=\frac{-1}{0.25}

\Rightarrow m_2=-4

Point-slope intercept formula:

y-y_1=m(x-x_1)

x_1=-6, y_1=8 and m=-4

Substitute these in the formula, we get

y-8=-4(x-(-6))

y-8=-4(x+6)

y-8=-4x-24

Add 8 on both sides of the equation.

y-8+8=-4x-24+8

y=-4x-16

Hence the equation of a line that is perpendicular to the given line is

y = –4x – 16

Find the slope between the points (-3, -2) and (5, 4) (type in integer or reduced fraction you found only)
DiKsa [7]

Answer:

The slope is: \frac{3}{4}

Step-by-step explanation:

The equation for slope is:

m=\frac{y_{2}- y_{1} }{x_{2} -x_{1} }

Point 1: -3=x_{1}, -2=y_{1}

Point 2: 5=x_{2}, 4=y_{2}

4-(-2)=6

5- (-3)=8

6/8=3/4
