Question

Please please help me out

Answer 1

Answer: y = 3x + 1

Explanation:

The equation is in Slope-Intercept format: y = mx + b where

• m is the slope (difference in y's over difference in x's)
• b is the y-intercept (value of y when x = 0)

`m=(y_2-y_1)/(x_2-x_1)\\\\\\\text{Let }(x_1,y_1)=(0,1)\quad \text{and}\quad \text{let }(x_2, y_2)=(1,4)\quad then\\\\m=(4-1)/(1-0)=(3)/(1)=3`

b = 1 refer to the table that shows y = 1 when x = 0

Now input m = 3 and b = 1 into the Slope-Intercept formula:

y = 3x + 1
