Find the number pattern within them
Such as 4-1 = 3
3-2=1
1-3= -2
Next three count up but will be negative

If the numbers are next to each other you subtract them. You would add what ever you got to -2 and do the same just not the subtraction part.

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
