What does the line y = -3x - 3 look like?
1 answer:
Using the general format of a line, y = mx + c,
Where m = slope of the line, c = vertical intercept.
y = -3x -3, comparing to y = mx + c
Slope, m = -3, vertical intercept, c = -3.
For a negative slope, the line would be falling downwards from the left hand side of graph sheet to right hand side.
Slope = -3,
Vertical or y intercept is the point it cuts across the y axis, at this point, x = 0
y intercept = (0, -3)
x intercept, at this point, the value of y is zero.
y = -3x - 3
0 = -3x - 3
0 + 3x = -3
3x = -3
x = -3/3
x = -1.
x intercept = (-1, 0)
So we would plot the points (0, -3) and (-1, 0)

Answer:
152 square inches
Step-by-step Explanation:
To answer this, please look at the picture below. We can find the area by separating and combine the value of areas after calculating three values for each areas. (Notice that when we separate them, we get three rectangles which we can use the formula of width × length)
We should get 80+48+24 which add up to 152.
