45x+angle trs = 180 straight line
angle trs = 180-45x
angle trs + angle t + angle tsr = 180 (sum of angles in a triangle =180)
(180-45x) + 25x + 57+x = 180
combine like terms
180 +57 -45x+25x+x=180
237-19x=180
subtract 237 from each side
-19x =-57
divide by -19
x=3
Answer:
Y= -1/2x + 1
Step-by-step explanation:
The equation for a line is Y=Mx+B
M stands for the Slope.
-Slope is rise/run. So, for this graph the line "rises" 1 point and "runs" left 2 points until meeting the line again. This slope is negative because it "runs" to the left.
B stands for the Y-Intercept
-The Y-intercept is the point at which the line crosses the Y axis. For this example, the line crosses the Y-intercept at (0,1).
Start by graphing y = |x|. Its vertex is at (0,0), and the graph opens up.
Now translate the entire graph 4 units up. The new vertex will be at (0,4). Draw an empty circle around this point.
Darken the graph of y = |x|+4 ONLY for the part which is left of the y-axis.
Now plot a dark dot at (0,4). Draw a dark, horiz. line from that dot to the right.
That's it!
