Find an equation of the tangent line to the curve at the point (1,1/e). y=x^4*e^-x
my attempt:
y'=(4x^3*e^-*e^-x)
y-y1=m(x-x1)
y-(1/e)=(4x^3)(e^-)(e^--1)
y=4x^4 e^-x - x^5 e^-x - 4x^3 e^-x + x^4 e^-x +1/e

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.
