PLZ HELP...Enter in standard form the equation of the line passing through the given point and having the given slope.
Alenkinab [10]

Standard form for the equation of the line is

$y=-\frac{2}{3} x-\frac{25}{3}

Solution:

Given point is (2, –5).

slope of the line m = -\frac{2}{3}

Here, x_1=2, y_1=-5

Equation of a line passing through the point:

y-y_1=m(x-x_1)

$y-(-5)=-\frac{2}{3} (x-(-5))

$y+5=-\frac{2}{3} (x+5)

$y+5=-\frac{2}{3} x-\frac{10}{3}

Subtract 15 from both sides of the equation.

$y+5-5=-\frac{2}{3} x-\frac{10}{3}-5

$y=-\frac{2}{3} x-\frac{25}{3}

Standard form for the equation of the line is

$y=-\frac{2}{3} x-\frac{25}{3}

Answer:

Value of a in term of x = 8/x

Step-by-step explanation:

Given:

14 = ax + 6

Find:

Value of a in term of x

Computation:

⇒ 14 = ax + 6

Step 1; Subtract 6 from both side

⇒ 14 - 6 = ax + 6 - 6

We get step 2

⇒ 8 = ax

Divide x from both side and we get step 3

⇒ 8 / x = ax / x

Step 4

⇒ 8/x = a

Step 5

⇒ a = 8/x

Value of a in term of x = 8/x

The empty cells in the table by determining all terms, constants, and coefficients for both algebraic expressions will be:

  • Constant = -3
  • Coefficient = -4, -5

<h3>How to illustrate the information?</h3>

In the first expression, the equation is given as 4a² - 5a - 3 while in the second expression, the equation is given as 7(-3x + 5) + 11y.

In this second expression, the term is 7(3x + 5), 11y. The constants are -7 and 5. Lastly, the coefficients are -3, and 11.
