Yea no solution is your answer
$13 (?) off the original price of 240 is 229. She will have to pay $229.00
<span>29+10j= -11
</span><span>29+10j - 29 = -11 - 29 (subtract 29 to both sides)
10j = -40
10j/10 = -40/10 (divide both sides by 10)
j = -4

You would just plug the values into the slope-intercept formula which is y=mx+b. m is representative of the slope, and b is representative of the y-intercept. The equation would be y=-9x+5
