Answer:
Step-by-step explanation:Example 1: Find the equation of the line passing through the points (–1, –2) and (2, 7).
Step 1: Find the slope of the line.
To find the slope of the line passing through these two points we need to use the slope
formula:
( )
( )
So the slope of the slope of the line passing through these two points is 3.
Step 2: Use the slope to find the y-intercept.
Now that we know the slope of the line is 3 we can plug the slope into the equation and
we get:
y = 3x + b
Next choose one of the two point to plug in for the values of x and y. It does not matter
which one of the two points you choose because you should get the same answer in either
case. I generally just choose the first point listed so I don’t have to worry about which
one I should choose.
(–1, –2) → –2 = 3(–1) + b Multiply to simplify the problem.
–2 = –3 + b Solve for b and you will have the y-intercept.
b = 1
X = -2
where the X co-ordinate always stays the same
Answer:
The answer is 4 5/12
Step-by-step explanation:
5/3 + 11/4
=5x4 - 3x4 + 11x3 - 4x3
=20/12 + 33/12
=53/12
Simplified
= 4 5/12
Hope this helps. :D
