Answer:
y=1/3x-4
Step-by-step explanation:
the slope-intercept format of the line is y=mx+b, where m is the slope and b is the y intercept.
we are given the slope (1/3) and the y intercpet (-4).
substitute the numbers into the equation
y=1/3x-4
the answer is y=1/3x-4
hope this helps!
Answer:
(2,2)
Step-by-step explanation:
Given equations
x-3y=-4-------------------------------(1)
y=-3x+8.------------------------------(2)
Substitute 2 in 1. This means use the value of y in equation 1, to replace y
x-3(-3x+8)=-4------------------open brackets
x+9x-24=-4---------------------collect like terms
10x=-4+24
10x=20---------------------------divide by 10 both sides to get value of x
10x/10=20/10=2
x=2------------------------------use value of x in equation (2) to get value of y
y=-3x+8
y=-3(2)+8
y=-6+8=2
solutions
x=2, y=2
