When you're given a point and the slope of a line, it is often easiest to write its equation in point-slope form.
This is
, where 
is the ordered pair for the point you are given and m is the slope.
Here, you would write
. Then, you simplify to get to slope-intercept form, which is 
, where b is the y-intercept.
The correct answer is A.
This is
Here, you would write
The correct answer is A.

Step-by-step explanation:
<u>Surface Areas </u>
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
The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus
The back left area is another rectangle of 4.5 mm by 9 mm
Finally, the back right area is a rectangle of 6 mm by 9 mm
Thus, the total surface area of the prism is
