If a line passes through points(-2,-4) and (3,-2), the equation of the line is y +2 = 2/5(x-_____)

1 answer:

7 0

We have the formula: (y+4)/(-2+4) = (x+2)/(3+2);
Then, (y+4)/2 = (x+2)/5;
y+4 = (2/5)(x+2); / - 2
y+2 =(2x)/5 + 4/5 - 2;
y + 2 = (2x)/5 - 6/5;
y + 2 = (2/5)(x - 3) is the equation of the line;

Surface Areas

Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.

Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is

$\displaystyle A_t=2*\frac{b.h}{2}=b.h=(4.5)(6)=27 mm^2$
