write the equation given the slope and y-intercept

1.) m= 1, b=2

2.) m= 1/4, b=0

3.) m= -3, b= 0.5

4.) m= 0.2, b=0.8

Need this asap if anyone can i would be very grateful. if you could show workings that would really

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

The frequency table shows the results of a survey comparing the number of beach towels sold for full price and at a discount during each of the three summer months. the store owner converts the frequency table to a conditional relative frequency table by row. which value should he use for x? round to the nearest hundredth. 0.89 0.90 0.92 0.96
