U want to go x2 plus x so its x3 then 4x3times -15 so x=3.33333
Answer:
(x, y) = (1, 3)
Step-by-step explanation:
given the 2 equations
x + y = 4 → (1)
y = 3x → (2)
Substitute y = 3x into (1)
x + 3x = 4
4x = 4 ( divide both sides by 4 )
x = 1
Substitute x = 1 into (2) for corresponding value of y
y = 3 × 1 = 3
solution is (1, 3 )
Hello there!
The slope intercept form is:

And if you need the slope intercept form y=mx + b to find the slope m
m = 13/11
I hope this helps!
