Answer:

(9+d) - 6

Step-by-step explanation:

6 less than the sum of 9 and d

First we do the sum since less than means it comes after

(9+d)

Then subtract 6

(9+d) - 6

Complete the equation of the line through (-6,5)(−6,5)left parenthesis, minus, 6, comma, 5, right parenthesis and (-3,-3)(−3,−3)

sladkih [1.3K]

Answer:

The equation of the line passing through the given points is:

$y=-\frac{8}{3}x-11$

Step-by-step explanation:

Given:

The two points are: $(x_1,y_1)=(-6,5)\textrm{ and }(x_2,y_2)=(-3,-3)$

The equation of a line when two points are given is:

$y-y_1=\left (\frac{y_2-y_1}{x_2-x_1} \right )(x-x_1)$

Plug in all the values and simplify.

$y-5=\left (\frac{-3-5}{-3-(-6)} \right )(x-(-6))\\y-5=\left (\frac{-8}{-3+6} \right )(x+6)\\y-5=\left (\frac{-8}{3} \right )(x+6)\\y-5=\frac{-8}{3}x-16\\y=\frac{-8}{3}x-16+5\\\\y=-\frac{8}{3}x-11$

Therefore, the equation of the line passing through the above points is

$y=-\frac{8}{3}x-11$

Use the given conditions to write an equation for the line in point-slope form and in slope-intercept form.

rodikova [14]

Point-Slope Form is y + 7 = - 4( x + 5)
Slope-Intercept Form is y = - 4x - 27

Parallel equations have the same slope. The point-slope formula is basically y minus the given y-coordinate of the ordered pair, set equal to the slope being distributed to x minus the given x-coordinate. (If that explanation was complicated, you can just google the formula.) In order to find the slope-intercept form, you can use the point slope form and plug in zero for x to find the y-value that would be your y-intercept.
