Write in point slope form an equation of the line through each pair of points:

EastWind [94]

Step-by-step explanation:

1.) (-2, 3) and (2, 9)

let (-2, 3) be (x1,y1) and (2, 9) be (x2,y2)

slope (m)=y2-y1

x2-x1

=9-3

2-(-2)

=9-3

2+2

=6

=3

2.) (0, 7) and (3, 5)

let (0,7) be (x1,y1) and (3,5) be (x2,y2)

slope (m)=y2-y1

x2-x1

=5-7

3-0

=-2

3.) (-2, -3) and (2, -1)

let (-2, -3) be (x1,y1) and (2, -1) be (x2,y2)

slope (m)=y2-y1

x2-x1

=-1-(-3)

2-(-3)

=1+3

2+3

4.) (-5, -2) and (-3, 8)

let (-5,-2) be (x1,y1) and (-3,8) be (x2,y2)

slope (m)=y2-y1

x2-x1

=8-(-2)

-3-(-5)

=8+2

-3+5

=10

5.) (-12, 20) and (-21, 29)

let (-12,20) be (x1,y1) and (-21,29) be (x2,y2)

slope (m)=y2-y1

x2-x1

=29-20

-21-(-12)

=29-20

-21+12

=9

-9

=-1

6.) (11, 8) and (-2, -3)

let (11,8) be (x1,y1) and (-2,-3) be (x2,y2)

slope (m)=y2-y1

x2-x1

=-3-11

-2-8

=-8

What two numbers will you add together that will give 32 and when you multiply it will give 48

motikmotik

Answer:

the two numbers are 30 and 2

Step-by-step explanation:

form two equations ie. a+b=32

a*b=48

express b in terms of a ie. b=32-a

substitute that equation to the equation a*b=48

to form a*(32-a)=48

open the brackets to get 32a-a^2 =48

using the quadratic formula

round off your answer to get 30 and 2

Solve the following systems by graphing. 1. x + 2y = 4 2x -y = 3

valina [46]

Given:

The system of linear equations are $x+2y=4$ and $2x-y=3$

We need to determine the solution to the system of equations by graphing.

Graphing the equation $x+2y=4$ :

To graph the equation $x+2y=4$ , let us determine the x and y intercepts.

x - intercept: When y = 0, then $x+2(0)=4 \implies x=4$

y - intercept: When x = 0, then $0+2y=4 \implies y=2$

The coordinates are (4,0) and (0,2)

Thus, the joining the coordinates of x and y intercept, we get the line for the equation $x+2y=4$

Graphing the equation $2x-y=3$ :

To graph the equation $2x-y=3$ , let us determine the x and y intercepts.

x - intercept: When y = 0, then $2x-0=3 \implies x=-1.5$

y - intercept: When x = 0, then $2(0)-y=3 \implies y=-3$

The coordinates are (-1.5,0) and (0,-3)

Thus, joining the coordinates of x and y intercepts, we get the line for the equation $2x-y=3$

Solution:

The solution of the two equations is the point of intersection of two lines in the graph.

Let us determine the solution using substitution method.

Substituting $x=4-2y$ in the equation $2x-y=3$ , we get;

$2(4-2y)-y=3$

$8-4y-y=3$

$8-5y=3$

$-5y=-5$

$y=1$

Thus, the value of y is 1.

Substituting $y=1$ in the equation $2x-y=3$ , we have;

$2x-1=3$

$2x=4$

$x=2$

Thus, the value of x is 2.

Therefore, the solution of the system of equations is (2,1)
