Listen to me very attentively.
The equation of the straight line with the slope "m", which passes through the point (a,b) is
y - b = m*(x-a).
Did you get it ?
Now apply this rule to your case and solve your problem on your own.
You can send me your solution/answer through the TY notes, if you want.
Also, you can submit your question by the same way, if you need.
Do not forget to sent your thanks to me after completing.
