Mathematics
1 answer:
Tpy6a [65]2 years ago
8 0

Answer:

(-2,2)

Step-by-step explanation:

Substitute answer for y in first equation (y=x + 4) into y of second equation

x+4=-2x-2

3x=-6

x=-2

put value of x (-2) into either equation to solve for y

y=x+4

y=-2+4

y=2

or y=-2x-2

y=-2(-2)-2

y=4-2

y=2

If the passes through points (-4,-6) and ( 2 ,6), the rate of change of the line is equal to
Delvig [45]

Answer:

2

Step-by-step explanation:

Use rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(6 + 6) / (2 + 4)

12/6

= 2

So, the rate of change is 2

Determine the equation of each line with the following properties:
iris [78.8K]

Answer:

a) y =2/3 x + 7.

b) x = -1

c) y = -4/5 x - 1/5

d) y = -3/2 x + 5/2.

Step-by-step explanation:

a) Intercept form y = mx + b where m = 2/3 and  b = 7

b) y can take any value but x is always -1.

c) Slope m = (-1-3)/ (1 - -4)

= -4/5

Using point-slope form where m = -4/5 and x1 y1 = 1 , -1:

y - y1 = m(x - x1)

y - -1 = -4/5(x - 1)

y + 1 = -4/5x + 4/5

y = -4/5 x - 1/5

d)  The slope m of the line perpendicular to this line is:

-1 / 2/3

m = -3/2.

When x = -1 , y = 4 so using the slope intercept form of a line

y = mx + b

4 = -3/2 * -1 + b  where b = the y-intercept.

4 = 3/2 + b

b = 4 - 3/2 = 5/2.

The equation is  y = -3/2 x + 5/2.

Which is the longest?<br> A. 2 km<br> B. 25 m<br> C. 2,500 cm<br> D. 3,000 mm
Leona [35]
2km=2000m
25m=25m
2500cm=25m
3000mm=3m

Hence the longest is 2km=2000m
