The line equation in slope-intercept form is $\"\"$ , where m is the slope and b is the y-intercept.

First find the slope of the line.

$\"\"$

$\"\"$ (Substitute 0for x₁, 1 for y₁, 1 for x₂ and 4 for y₂)

$\"\"$ (Simplify)

$\"\"$ (Divide: $\"\"$ )

$\"\"$

Next find the y-intercept.

The line crosses the y-axis at (0, 1).

So, the y-intercept is 1.

$\"\"$

Replace m with 3 and b with 1 in the equation $\"\"$ .

The slope-intercept form line equation is $\"\"$ .
