Answer:
y = [tex]\frac{1}{2}[/tex]x
Step-by-step explanation:
identify two points on the line: (2, 1) (4, 2) to find the slope([tex]\frac{y2 - y1 }{x2 - x1}[/tex]) for the line
=> [tex]\frac{2- 1}{4-2}[/tex] => [tex]\frac{1}{2}[/tex]
find the y-intercept:
=> 0
substitute the slope and y-intercept into the equation y = mx + b
slope ↑ ↑ y-intercept
=> y = [tex]\frac{1}{2}[/tex]x + 0
=> y = [tex]\frac{1}{2}[/tex]x
