Answer:

m= y2 - y1

x2 - x1

m= -7 + 3 ( I have + 3 and 4 because when negative cancel negative, it is

-2 + 4 positive)

= -4 = 2

-2

Step-by-step explanation:

write down the formula for finding slope.
replace the y's and x's with the values.
add everything together
divide

A perpendicular bisector, CD is drawn through point C on AB.

STALIN [3.7K]

Answer

B(18/5,0)

Explanation

First we find the coordinates of C;

C (x, y) = [(-3+7)/2, (2+6)/2]

= (2, 4)

Find the equation of CD.

slope = (6-2)/(7--3)

= 4/10 = 2/5

slope of CD = -5/2

-5/2 = (y - 4)/(x - 2)

-5/2(x - 2) = y - 4

(-5/2) x + 5 = y - 4

y = (-5/2)x + 9

For the x-intercept y = 0

∴ y = (-5/2)x + 9

0 = (-5/2)x + 9

5/2 x = 9

x = 2/5 × 9

= 18/5

x-intercept = (18/5, 0)

Solve the system of linear equations by graphing. y = –5/2 x – 7 x + 2y = 4 What is the solution to the system of linear equatio

Anestetic [448]

Keywords

system; linear equations; graphing; solution

we have

$y=-\frac{5}{2}x-7$ -------> equation A

$x+2y=4$

$x=4-2y$ ----> equation B

The system of linear equations is composed of equation A and equation B

Substitute the equation B in equation A

$y=-\frac{5}{2}[4-2y]-7$

$y=-10+5y-7$

$4y=17$

$y=17/4=4.25$

Find the value of x

$x=4-2[17/4]=-4.5$

The solution is the point $(-4.5,4.25)$

Using a graphing tool

see the attached figure

therefore

the answer is the option A

$(-4.5,4.25)$
