Answer:
y = x -7
Step-by-step explanation:
y2 - y1 / x2 - x1
-5 - (-2) / 2 - 5
-3/-3
1
y = x + b
-2 = 5 + b
-7 = b
y = -7
y = x -7

Answer:
(7/3) x^3 ln x - (7/9) x^3 + c.
Step-by-step explanation:
∫udv = uv - ∫vdu
u = ln x and dv = 7x^2dx so,
du = 1/x and v = 7x^3/3 so:
∫7x^2 ln x = (7x^3/3) ln x - 7 ∫x^3/3 * 1/x dx
= 7/3 x^3 ln x - 7 ∫x^2/3 dx
= 7/3 x^3 ln x - 7/x^3/2 * 1/3 dx
= 7/3 x^3 ln x - 7/9 x^3 + c.
