-4 - 10x

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.

What is the slope of a line that is perpendicular to y = 3x + 1

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)
