Given the points:
A (-1, 3) and B (0, 4)
slope - intercept form of an equation: y = mx + b.
[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex][tex]m\text{ = }\frac{4-3}{0\text{ + 1}}=\text{ 1}[/tex]
Now, to find b, we can replace one point in the slope- intercept form:
4 = 1 x 0 + b
b = 4
Slope- intercept equation: y = x + 4
