A straight line in the xy- plane has y-intercept of 17 . If the slope is half its y-intercept, and the x-coordinate of the point in this line is 7, find the y-coordinate.	Select:
A) -100
B) 34
C) 76.5
D) 75.6
E) 74.3
Eq of line = Y = MX +76.5   76.5= 17   M=76.5/2 = 17/2 =   X = 7   Substitute givens:   Y=(17/2*7) + 17= 
<gadget id="calculator">(17/2*7) + 17</gadget>
<output>153/2 = around 76.5</output>
76.5   correct option is 76.5
<result>C</result>
