What is the formula for the following arithmetic sequence?

12, 6, 0, -6, ...

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Find the slope of a line given the following two points

Two variables, x and y, vary inversely, and x=12 when y=4. what is the value of y when x=3?
