1. (-2, 14)

Simply plug in the points

2.k=8

Plug in -1 as X and solve for y
This gives the k value as well

3. y=-5x + 12

Use the point slope formula
Y2-Y1= m(x2-x1) + b

Answer:

1.)  Ans  -2 , 14

2.) Ans 2 1/5

3.) Ans y= mx+c

Step-by-step explanation:

first one you use Y = Mx +c

You see the Mx is a multiplication

and you input.

M * x = -5 x 2

M* x = -5 x -1

M* x = -5 x 3

M* x = -5 x -2

and note the answers will be less 4 as the equation states +4 is the y intercept and balances the equation.

So answers of the above in same order are;

-10

5

-15

10

we add 4

-6

9

-11

14

and see that 14 is the correct answer for y.

So the correct coordinates are -2, 14

Question 2) coordinates -1 k can equal = -5x+3

First we write as a division we know the gradient is -5

-we eliminate x

5x-1 / k+3  

= 4x/k+3

M = -5

= 4x = -5(k+3)

= 4x = -5k +15

= 4x -15 =-5k

= -11 =-5k

= 11/-5 = k

k = 2 1/5

3) Ans The equation of a line is y=(input the number whatever times the x to make the number before you add)

y = m

3) Ans then you place x next to it

3) Ans then you place + 4 or whatever adds to the number.

So the equation of the line is what makes y its value through m the gradient being the number you times with x and the difference of that total to make y intercept.

Find y intercept and you have c of  Mx+c
