For question 4: you have to do (y2 - y1) divided by (x2 - x1) to get the rise over run...

5-2
——. = 3/4
11 - 7


For question 5: input the values of x,y and the gradient into the equation of a line.....

y = mx+ c

-8 = 3(-2) + c

-8 = -6 + c

-2 = c

therefore:

y = 3x - 2

Hope this helps! Any questions let me know :)

Answer:

4 is c; 5 is a

Step-by-step explanation:

Given points for 4: (7, 2), (11, 5)

Given info for 5: (-2, -8); slope of  3

point-slope formula: y2 - y1 = m(x2 - x1)

Plugging in points: 5 - 2 = m(11 - 7)

Now we solve for m.

3 = m4

Final step: divide both sides by 4

Answer: m = 3/4

Second equation!

Plug into point-slope formula: y + 8 = 3(x + 2)

Distributive property of equality to eliminate parentheses

y + 8 = 3x + 6

Get y by itself by subtracting 8 to both sides

y = 3x - 2

What is the equation of the line perpendicular to –x + y = 7 and passing through (-1, -1)?
Vesna [10]
- x + y = 7
y = x + 7
slope = 1
perpendicular slope = -1

at point (-1, -1),
y = mx + c
-1 = -1 (-1) + c
-1 = 1 + c 
c = -1 -1
c = - 2

equation:
y = -x -2
y + x = -2 or - x - y = 2
