What is an equation for the line that passes through (-2,-3) with a slope of -1/2?

Crazy boy [7]

Answer:

Step-by-step explanation:

To write the equation of a line use the point slope form of a line substituting m = -1/2 and the point (-2,-3).

$y -y_1 = m(x-x_1)\\y --3=-\frac{1}{2}(x--2)\\y+3 = -\frac{1}{2}(x+2)$

Convert to standard form by applying the distributive property and rearranging the terms.

$y + 3 = -\frac{1}{2}(x+2)\\y+3 = -\frac{1}{2}x -1\\2y + 6 = -x -2\\x+2y + 6 = -2\\x + 2y = -8$

The equation x +2y = -8 is the same equation as 4y + 2x = -16 just doubled----> 2x + 4y = -16

2d +9= 19

The solution is d =

${\huge{\boxed{\mathbb{ANSWER\:WITH\:EXPLANATION}}}$

Hello there, first we can place our equation, which you have stated

$2d+9=19$ , this algebra, in algebra we want to find the exact value of the variable, or have the variable on one side of the equation.

First we can subtract $9$ with both sides of the equation giving us the result of $2d=10$ , this can also be represented as $2\cdot d=10$ , now just divide both sides of the equation by $2$ , our answer is $d=5$ .
