Answer:

The answer is: y = 3/8x + 28/8

Step-by-step explanation:

Given point: (4, 5)

Given slope m = 3/8

Uset the point slope form:

y - y1 = m(x - x1)

y - 5 = 3/8(x - 4)

y - 5 = 3/8x - 12/8

y = 3/8x - 12/8 + 5

y = 3/8x - 12/8 + 40/8

y = 3/8x + 28/8

Proof, use point (4, 5):

f(x) = 3/8x + 28/8

f(4) = 3/8(4) + 28/8

= 12/8 + 28/8

=40/8 = 5, giving (4, 5)

The line integral of xydx×x^2y^3dy where c is the triangle with points (0,0) (1,0) (1,2) using green's theorem

lyudmila [28]

If $\mathcal C$ is the boundary of the triangle $D$ , then by Green's theorem

$\displaystyle\int_{\mathcal C}xy\,\mathrm dx+x^2y^3\,\mathrm dy=\iint_D\left(\frac{\partial(x^2y^3)}{\partial x}-\frac{\partial(xy)}{\partial y}\right)\,\mathrm dA$
$=\displaystyle\int_{x=0}^{x=1}\int_{y=0}^{y=2x}(2xy^3-x)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x\int_{y=0}^{y=2x}(2y^3-1)\,\mathrm dy\,\mathrm dx$
$=\displaystyle\int_{x=0}^{x=1}x(8x^4-2x)\,\mathrm dx=\frac23$
