INFINITE answers to this question..... here is ONE

34 x 2

Yep.....could be either !

Find the slope first   =  rise / run  =  (y2-y1)/(x2-x1)        It does not matter which point you ascribe to '1' or '2'

m=slope = (7-2)/(7-2) = 5/5 = 1 

so y = mx + b   becomes   y= x + b    (m= slope = 1)

Plug one of your points into the equation to find 'b'

7 = 7 + b      so b = 0

your y =mx+b equation of a line becomes  y= x    because m= 1  and b= 0

y=mx+b =

y=(1)x + 0

2x + y > 5         There are infinite solutions to this problem.....for a DISCRETE (x,y) you would need a SECOND equation relating x and y to solve.....Sorry....

3+4 = 989 - 982

Parabola   y = x^2 

  when x= a    y = a^2

Slope = 2x    (derivative of x^2)

y=mx+b   yields    a^2 = 2a(a) + b      

                              a^2 = 2a^2 + b

                              0 = a^2 + b

                               b= -a^2

  so   y = mx + b becomes        y = 2x(x) - a^2            When x = 0   y = - a^2  

Yah?   

Really???   Just use the calculator!

(60) / (3/4)   =   60  x  4/3 =  240/3 = 80

18 x ? = 7500000000      Divide both sides by 18

? = 7500000000/18 = 416666666.6666666666666667

To ADD or SUBTRACT fractions, you will need to have a COMMON DENOMINATOR

22   is common to 11 and 2

-1/2  x 11/11 = -11/22

3 (9/11) = 42/11    42/11 x 2/2 =  84 / 22

Now you can add them

-11/22 + 84/22 = (-11+84)/22 = 73/22 = 3 7/22
