Y=-2x-5
You can divide by -2 on both sides of the equal sign getting the answer above.

SOMEONE, PLEASE HELP ME WITH THIS PLSSSS

Stels [109]

Answer:

Step-by-step explanation:

1. You can use the intercepts to graph the line. The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.

2. Point-Slope Form: y - y1 = m(x - x1)

Standard Form: ax + by = c

5x - 2y = 10

-2y = -5x + 10

y = (5/2)x - 5 The slope is 5/2.

y - 2 = (-5/2)(x - 10)

y = (-5/2)x + 25 + 2

y = (-5/2)x + 27 The slope is -5/2.

y = (-5/2)x - 10 The slope is -5/2.

Write a in slope-intercept form of the line that passes threw (-9,5) and (-3,3)

Amanda [17]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}$

We have the following points:

$(x_ {1}, y_ {1}): (- 9,5)\\(x_ {2}, y_ {2}): (- 3,3)$

Substituting we have:

$m = \frac {3-5} {- 3 - (- 9)}\\m = \frac {-2} {- 3 + 9}\\m = \frac {-2} {6}\\m = - \frac {1} {3}$

Thus, the equation is of the form:

$y = - \frac {1} {3} x + b$

We substitute one of the points and find "b":

$3 = - \frac {1} {3} (- 3) + b\\3 = 1 + b\\3-1 = b\\b = 2$

Finally, the equation is of the form:

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

Answer:

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