Answer:
Step-by-step explanation:
We first need to find the slope of the given line. Putting that standard form of a line into slope intercept:
12y = -3x - 6 so

In this form we can easily determine that our slope is -1/4. That means that the perpendicular slope, the opposite reciprocal, is +4. We will write first the point slope of the new line using our given point, then solve it for y, putting it into slope-intercept form. y - (-7) = 4(x - (-1)) and
y + 7 = 4x + 4 so
y = 4x + 4 - 7 so
y = 4x - 3
Answer:
there are 16 1/4s
Step-by-step explanation:
1 = 1/4 x 4
2 1/2 + 4 = 6 1/2
4 = 1/4 x 16
The base requires (4 ft)*(3 ft) = 12 ft^2.
The sides require (2 ft)*(2*(4 ft +3 ft)) = 28 ft^2.
The total area of the box is (12 +28) ft^2 = 40 ft^2. . . . . . . . . 1st selection
