Answer:

Answer: Option D.

Step-by-step explanation:

Hey there!!

Here, To find the equation of a st.line passing through point (3,1) is :

(y - 1) = m1(x - 3)

It is the first equation.

Given, Another equation is:

y =  \frac{2}{3} x + 1

It is 2nd equation.

Comparing the 2nd equation with y = mx+c we get,

Slope (m2) = 2/3.

As per the condition of parallel lines,

m1 = m2 = 2/3.

Putting, the value of m1 in equation 1st we get,

(y - 1) =  \frac{2}{3} (x - 3)

or, 3 (y-1) = 2(x-3)

or, 3y - 3 = 2x - 6

y =  \frac{2x - 6 + 3}{3}

y =  \frac{2}{3} x - 1

Diving-3/3 = -1.

Therefore, y = 2/3 x - 1 is the required equation.

Solve x&lt;3 and x≥−1 and write the solution in interval notation. If there is no solution, type ∅ .
bearhunter [10]

Shown in the Figure below

Step-by-step explanation:

In this exercise, we have the following system of inequalities:

x

The word and means intersection, so both inequalities must be true at the same time. We can graph this system as indicated in the figure below. Indeed, there is intersection between -1 and 1. Also, the number -1 is included in the solution because x\geq -1 and this is represented by the closed circle. On the other hand, the number 3 is not included in the solution because x and this is represented by the open circle.
