Answer:
x=1
y=-4
Step-by-step explanation:
Since -x-3=y subsitue that in at the top equation
Plug x=1 back into the equation to solve for y.
Guys this might seem annoying because I just added a question few mins ago but I got home only about 5 to 10 mins ago and I have
to go to bed soon and I gotta finish my hw
Sorry, here is my question 20 points for it I’m kinda low on them too so small amounts of points, I’ll make up for it tomorrow thanks so much :’)

Answer/Step-by-step explanation:
✍️The equation of the line in point-slope form:
The equation is given as , where,
(a, b) = a point on the line.
Let's find the slope (m) of the line, housing (3, 21) and (6, 12):
Substitute a = 3 and b = 21, m = -3 into .
Thus, the point-slope equation would be:
✅
✍️The equation of the line in slope-intercept form:
Rewrite , so that y is made the subject of the formula.
Add 21 to both sides
✅The slope-intercept equation of the line is
Where,
-3 = how much did his delivery time decrease per day (slope)
30 = how long it initially took Peter to deliver his packages (y-intercept)
