Write an equation of the line in slope-intercept form

y = x + 4

Step-by-step explanation:

Well, the important thing is to get the slope first. The slope here is 1.

Here's how to find the slope yourself:

m (slope) = (y₁ - y₂)/x₁ - x₂

m (slope) = (3 - 4)/(-1 - 0)

m (slope) = -1/-1

m (slope) = 1

So, we found the slope. Now, plug it into the equation. y = 1x + b. Cool, so now let's choose the first point to solve this.

So, 3 = 1(-1) + b

3 = -1 + b

3+1 = -1+1 + b

The ones cancel out...

4 = b

So, now you plug that into the equation... y = 1x + 4, although you would write it as y = x + 4.

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
