Answer:
y = 2x - 2
Step-by-step explanation:
Points on graph: (4,6) and (2, 2)
<u>Slope:</u>
m=(y2-y1)/(x2-x1)
m=(2-6)/(2-4)
m=(-4)/(-2)
m = 2
<u />
<u>Slope-intercept:</u>
y - y1 = m(x - x1)
y - 6 = 2(x - 4)
y - 6 = 2x - 8
y = 2x - 2
0.175 = 17.5%
0.14 = 14 %
0.86 = 86%
0.21 = 21%
0.178 = 17.8%
0.81 = 81%
ALL YOU HAVE TO DO TO FIND THE PERCENTAGE IS MOVE THE POINT TWO (2) PLACES TO THE RIGHT FROM IT'S PREVIOUS POSITION...
