For the y-intercept, look at the graph, and find the point of intersection of the line and the y-axis. You will see that the line and the y-axis intersect at 3.
The y-intercept is 3.
To find the slope, you need to find two points that are easy to read on the graph. You must go from one point to the other, but you can only move vertically and horizontally along grid lines. Look at (0, 3) and (4, 0). Slope is rise over run. Rise is up and down. Run is left and right. Start at (0, 3), the y-intercept. To go from that point to (4, 0), you go 3 units down. Down is negative, so the run is -3. Then you are at the origin, (0, 0). To go to (4, 0), now you go 4 units to the right. That is a run of 4. The rise is -3, and the run is 4.
slope = rise/run = -3/4
Since NELR is a parallelogram we have RN parallel to LE.
This means <RNE and <LEN are same side interior angles and add up to 180 degrees.
So we have 7x+33+11x+21 = 180
18x = 126 . x = 7
The answer would be 410 hope this helps
Answer:
18x + 16
Step-by-step explanation:
2 x length + 2 x width = perimeter
2(5x + 2) + 2(4x + 6)
= 10x + 4 + 8x + 12
= 18x + 16
