Answer:

y=-\frac{1}{2}x-8

Step-by-step explanation:

(-4,-6)(-2,-7)

Step 1. Find the slope (by using the slope-formula)

m = slope

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-7--6}{-2--4}

m=\frac{-1}{2}

m=-\frac{1}{2}

Step 2. Create the equation of a line that has a slope of -\frac{1}{2}

y=-\frac{1}{2} x+b

Step 3. Find the y-intercept

To do this, use any of the two points and substitute their x and y values

y=-\frac{1}{2}x+b

point: (-2,-7)

(-7)=-\frac{1}{2}(-2)+b

(-7)=1+b

b=-7-1

b=-8

Step 4. Write the equation in Slope-intercept form

y=mx+b

y=-\frac{1}{2} x-8

Answer:

\huge\boxed{\sf All \ right \ angles \ are \ congruent}

Step-by-step explanation:

Since it is given that HK ⊥ IJ, This means that it is a right bisector (Dividing the straight line into two angles of 90 degrees)

So,

∠HKI ≅ ∠HKJ (Both of tem are right angles and are equal to 90 degrees)

Alekssandra [29.7K]

Answer:

4x+8

Step-by-step explanation:

We have been given an expression 4(x+2). We are asked to find equivalent expression to our given expression.

Using distributive property a(b+c)=ab+ac, we will get:

4\cdot x+4\cdot2

4x+8

Therefore, the expression 4x+8 is equivalent to our given expression.
