Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40

Answer:
If it is in y=mx+b form, you use your slope.
Step-by-step explanation:
In the equation y=5x+0, you would graph a point at (0,0). Next you would go up five and to the right one b/c 5 is really 5/1. The top number tells up or down and the bottom number tells you left or right. Left/down is negative and right/up is positive. In the equation y=4x-3, you would plot a point at (0,-3). Then go up four and right one. In the equation y=1/5 x+4, you would plot a point at (0,4). Then go up one and to the right 5.
