The slope intercept form of the equation of a line that passes through point (-3, 8) is y
= - 4x + 6. What is the point-slope form
of the equation for this line?
y-3= -? (X + 8)
y +3= ? (- 8)
y+8= _?_(x-3)
y-8= -
(x + 3)

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
