Gradient of line= (y2-y1)/(x2-x1)
Gradient of line= (10-(-6))/(8-4)
Gradient of line= 16/4
Gradient of line= 4

Y-intercept
Y=4x+c
When x=8, y=10
10=32+c
c= -22

Equation of line
Y=4x-22

When x=b, y=2b
Y=4x-22
2b=4b-22
22=2b
b=11

Graph the equation. (x + 3)2 + (y + 2)2 = 16
Sati [7]

okay well first you should put it in slope-intercept form aka y = mx + b

but you have simplify everything first

2(x + 3) + 2(y + 2) = 16

2x + 3 + 2y + 4 = 16

2x + 2y + 7 = 16

              -7    -7  

2x + 2y = 9

-2x          -2x

2y = -2x + 9

/2         /2

y = -x + 4.5

so now in a graph it should look like this:

Megan will multiply the first equation by 3 then add the result to the second equation.
Nesterboy [21]

The resulting equation will be x + y = 4 and 4y =20

<h3>System of equation</h3>

GIven the system of equation given as:

x + y = 4

-3x + y = 8

If Megan multiplies the first equation by 3 then add the result to the second equation, the resulting equation will be:

3x  + 3y = 12

-3x + y = 8

Adding both equation

3y + y = 12 + 8

4y = 20

Hence the resulting equation will be x + y = 4 and 4y =20

N bisects MO. MN = 7x - 15, NO = 2x + 5. Find x
mrs_skeptik [129]

Answer:

x = 4

Step-by-step explanation:

I don't see a picture, so I'm assuming that M, N, O are points on a line segment with endpoints M and O.

Point N bisects segment MO, so it's in the middle of that segment.  That means the distance from M to N and the distance from N to O are equal.

7x - 15 = 2x + 5

5x - 15 = 5

5x = 20

x = 4
