Answer:y = 2x/3 - 5

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)

The equation of the given line is

3x+2y=12

We would rearrange it so that it will form of the y = mx + c. It becomes

2y = -3x + 12

y = -3x/2 + 6

Comparing with the slope intercept form, slope = - 3/2

If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the given line. Therefore, the slope of the line passing through (3,-3) is 2/3

To determine the intercept, we would substitute m = 2/3, x = 3 and y = -3 into y = mx + c. It becomes

- 3 = 2/3×3 + c = 2 + c

c = - 3 - 2 = - 5

The equation becomes

y = 2x/3 - 5

Refer to the number line. Find the coordinate of point D that is 7/16 M to J. of the distance from M to J.​
Usimov [2.4K]

The coordinate of point D that divides segment MJ in the ratio 7/16 is (13, 8)

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.

Let us assume that point M is at (20, 1) and point J is at (4, 17), hence:

If point D(x, y) is 7/16 M to J, then:

x = (7/16)(4 - 20) + 20 = 13

y = (7/16)(17 - 1) + 1 = 8

The coordinate of point D that divides segment MJ in the ratio 7/16 is (13, 8)

PLEASE HELP!!! In the diagram, line AB is a perpendicular bisector of segment CD. What is the length of CD?
ra1l [238]

Answer:

12

Step-by-step explanation:

AD is 6. a bisector splits a line in half. X would equal 6 meaning AD would equal 12.

Write the equation in y=mx+b form please????
Solnce55 [7]

ANSWER

y =  - 2x - 5

EXPLANATION

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

m =  \frac{y_2-y_1}{x_2-x_1}

This implies that;

m =  \frac{5 - 1}{ - 5 -  - 3}

m =  \frac{4}{ - 2}  =  - 2

We can now find the equation using the formula;

y-y_1=m(x-x_1)

y   - 1 =  - 2(x  + 3)

Expand:

y =  - 2x -6 + 1

y =  - 2x - 5
