A straight line has a slope of 1/2 and a y-intercept of -2. On this line, what is the x-coordinate of the point whose y-coordinate is 10? Choose the correct choice from the following choices.
A) (8) B) (12) C) (13) D) (16) E) (24)
For the point intercept form of a line y=mx+b ; m is the slope and (b=y when x=0)   Slope=y2−y1/ x2−x1   we are given slope =1/2   y intercept is always equal to b when x = 0 (therefore at origin we can always write any (x,y) pair as (0,b)   y intercept hence (b) is given -2   now we have got all the values that we want to calculate slope   1/2=10−(−2)/x−0   1/2=10+2/x==&gt;1/2=12/x==&gt;x=24   CORR(24)CT ANSW(24)R IS (24)
