Find the equation of the linear function represented by the table below in slope-intercept form.

x y

-1 1

2 13

5 25

8 37

Answer 1

Answer:

y = 4x +5

Slope is 4

Intercept is 5

Step-by-step explanation:

Using, y1= 1 and x1= -1

And, y2 = 13, x2 = 2

$\frac{y2 - y1}{x2 - x1} = \frac{y - y1}{x - x1}$

$\frac{13 - 1}{2 - ( - 1)} = \frac{y - 1}{x - ( - 1)}$

$\frac{12}{3} = \frac{y - 1}{x + 1}$

$4 = \frac{y - 1}{x + 1}$

$y - 1 = 4(x + 1)$

y-1 = 4x +4

y = 4x +4 +1 = 4x +5
