Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0 , y))
To find the slope(m), use the slope formula and plug in 2 points
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
(x₂ , y₂) should be the next point after(on the right of) (x₁ , y₁)
If the graph shows the line crossing the y-axis, you can easily find your y-intercept. But if it's not on the graph, you can use
y = mx + b and plug in the slope you found, and plug in a point for (x,y) to find b
