Answer:
is the equation of line in slope intercept form.
Step-by-step explanation:
Line runs through points begin ordered pair negative 3 comma 0 end ordered pair and begin ordered pair 0 comma 4.
First ordered pair: (-3,0)
Second ordered pair: (0,4)
We have two points and need to find equation of line in slope intercept form


y-intercept, when x=0 , (0,4)
Equation of line in slope intercept form:
y=mx+b
where,
and b=4
Required equation:

Thus,
is the equation of line in slope intercept form.
An acute triangle is triangle that's less than 90 degree angle and a right triangle is exactly 90 degree angle so
the answer is no, it is not possible
Answer:
they work together, it will take 2.4 hours to build the wall.
Step-by-step explanation:
One bricklayer can build a wall in 6 hours.
One hour work = 
Another bricklayer can build the same wall in 4 hours.
One hour work = 
They can together, how long will take them to build the wall.
Let's take "t" the time taken to build the wall.
The sum of their work rate = 1 (To build the wall)

Now we have to solve this equation. Take LCD of 6 and 4.
The LCD (least common divisor) of 6 and 4 is 12.

5t = 12*1
5t = 12
Dividing both sides by 5, we get
t = 
t = 2.4 hours.
So, they work together, it will take 2.4 hours to build the wall.
