Coordinates of the line are: (0, 2) & (3, 8) Write the equation is slope-intercept form

1 answer:

4 0

Here, First Calculate the slope:
m = y2-y1 / x2-x1
m = 8 - 2 / 3 - 0
m = 6 / 3
m = 2

Now, we know, y-y1 = m(x - x1)
y - 8 = 2(x - 3)
y - 8 = 2x - 6
y = 2x + 2

In short, Your Answer would be y = 2x + 2

Hope this helps!

Answer:

a. 29

b. 9.1

Step-by-step explanation:

General = The perimeter is all the sides added togther.

a. x is given to you, so you just add all the numbers.

b. Now the perimeter is given, but not x. So add the numbers you can see. That would be 9+6.5+4.7= 20.2

So something + 20.2 has to equal 29.3

29.3 - 20.2 = 9.1.

I did not answer c. because I'm not very confident that my answer would be right. With my explainaion I hope you can figure it out easily enough. Good Luck!

Use simultaneous equations solve the following problem.

Genrish500 [490]

Let E represent English test and M represent Math test.

M + E = 164

+ M - E = 22

2M = 186 eliminated E by adding the two equations

M = 93 divided both sides by 2

Now, plug that value into either of the equations to solve for E.

M - E = 22 → 93 - E = 22 → -E = 22 - 93 → -E = -71 → E = 71

Answer: Math = 93, English = 71
