Question

Help me please. I need to solve this.

Answer 1

The linear equation is : y = 3x -5

Using the data in the table, we can create a linear equation in the form ;

• y = bx + c ; b = slope , c = intercept

slope, b = Rise/ Run

b = (19 - 7) / (8 - 4) = 3

Now we have ;

y = 3x + c

using the pair of points; (4, 7)

7 = 3(4) + c

7 = 12 + c

c = -5

The linear equation is : y = 3x -5
