Can anyone be kind enough to tell me? 5. Is anyone kind enough to tell me?

Do you want it or don't want it.

If there are x brothers in their family, then there are x - 1 sisters.

x=2(x-1-1)

x=2x-4

x=4x-1=3

The missing limbs searched for 4 brothers and 3 sisters.

1)x+2y=4

y=-1/2x+2

Slope -1 2

Intercept 4 on the x-axis

Intercept 2 on the y-axis

2)y=2(x+3)=2x+6

The intercept of slope 2 on the x-axis 3

Intercept 6 on the y-axis

3)y-1=-3(x-2)

y=-3x+7

Slope -3 intercept on the x-axis 7 3

Zheng Xin on the y-axis truncated the bush of rotten distance 7

4)x/2+y/3=1

y=-3x/2+3

Slope -3 2

Intercept 2 on the x-axis wax drain

Intercept 3 on the y-axis

In the first problem, we will change the formula into the form of y=what x, and then draw the graph on the coordinate system. The way to draw is to take x, y=0 and find points on the coordinate system. You can find two points in the letter and connect them.

You can see the intercept. The slope is the number before x.

The second question is the same method.

The intercept in the y-axis is 6That is, when x=0, the celery, y=6The solvable m slope of the original problem is 2That is, the number in front of x is 2

Perpendicular to the x-axis is probably m=1. Marketing.

Haha, I don't know if it's right

One. Birds and phoenixes, stupid birds fly first, birds fly first, silkworm birds, Birds are poor, then the birds are pecked into the cage, birds and beasts are scattered, birds and beasts are scattered, birds are scattered, birds are scattered, birds cry and fall, birds cry and resent, birds are singing and fragrant, poor birds are in their arms, owls are winged, blue birds are diligent and light, birds are lifted, birds are seen as birds and beasts are scattered, people die for money, birds are killed for food, three-inch birds, seven-inch beaks hurt the bow, beasts and birds, beasts and birds, beasts gather and birds scatter, black birds private feelings, like ploughing birds, bears through birds, bears through birds, bears through birds, birds by birds, birds by people, birds by people, birds of birds

This number is multiplied by x9.

x=This number is.
