Hello : let the equation : y = ax+b <span>xx-intercept (4.5,0) : 0 = a(4.5) +b .... (1) </span><span>yy-intercept (0,-5.4) .: - 5.4 = a(0)+ b .....(2) by (2) : b = - 5.4 subsct in (1) : 4.5a -5.4 = 0 a = 5.4/4.5 a = 54/45 a = 6/5 </span><span>the equation of the line (in slope intercept form) is : y =(6/5)x - 5.4</span>
