Question

Y=-(1)/(2)x+2 what is the x-intercept and how to solve the problem

Answer 1

Hi, to know the x-int you have to solve for x for
$first \: step \\ y = \frac{1}{2} x + 2 \\ subtract \: two \: on \: both \: sides \\ y - 2 = \frac{1}{2} x + 2 - 2 \\ you \: end \: with \\ y - 2 = \frac{1}{2} x$
$now \: you \: multiply \: by \: the \: recipical \\ (y - 2)( \frac{2}{1} ) = \frac{1}{2} x\times \frac{2}{1} \\ your \: solution \: is \\ 2y - 4 = x \:$
