Explanation:
We first require to establish the relationship between x and y.
The equation of a line in
#color(blue)"slope-intercept form"# is.
#color(red)(bar(ul(|color(white)(2/2)color(black)(y=mx+b)color(white)(2/2)|)))#
where m represents the slope and b, the y-intercept.
#"here " m=-1.5" and " b=3#
#rArry=-1.5x+3" is the equation connecting x and y"# We can now calculate the value of y when x = 6
#x=6toy=(-1.5xx6)+3=-9+3=-6#
