Answer:

Step-by-step explanation:

If denominators are same, subtract the numerators.For example

6/8-1/8 here denominators for both fractions are same (8)

6-1/8 = 5/8

If denominators are different, find LCM for the denominators.

1/2 - 1/3 .Here LCM for 2 and 3 is 6

1*3/2*3 - 1*2/3*2 = 3/6 - 2/6    { now same denominator 6}

=(3-2)/6=1/6

Find the eqation of the line passing through the points(3,3) and (4,5)
Nikitich [7]

Answer:

The Answer is: y = 2x - 3

Step-by-step explanation:

Given points: (3, 3) and (4, 5)

Find the slope, m:

m = y - y1/(x - x1)

m = 3 - 5/(3 - 4)

m = -2/-1 = 2

Use the Point Slope form of the equation:

y - y1 = m(x - x1)

y - 5 = 2(x - 4)

y - 5 = 2x - 8

y = 2x - 8 + 5

y = 2x - 3

Proof:

f(3) = 2(3) - 3

= 6 - 3 = 3, giving (3, 3)
