Best ResponseYou've already chosen the best response.0you know m = 3/4. Take the first coordinate pair (1,1). Set y=1 and x=1. Then: \[1=3/4 + c\] \[c=1/4\] You can check this value by using the other coordinate pair (5,4) \[4=15/4 + c\] \[c=(1615)/4 = 1/4\] Therefore the equation of your line is \[y=\frac{3}{4}x + \frac{1}{4}\]

Best ResponseYou've already chosen the best response.0go back to the general equation of a line: \[y=mx+b\] in this case, m=0 so it' just \[y=b\] This tells you that the line is a straight line forever, parallel to the x axis and intersecting the y axis at 6. Now look at your two pairs of coordinates. y is 6 in both (it better be)! So the equation of your line is......?

Best ResponseYou've already chosen the best response.0yes \[y=6\] is the equation of your line, it's a very boring graph if you ask me

Best ResponseYou've already chosen the best response.1so what the equestions y=0x

Callum29

Best ResponseYou've already chosen the best response.1so whats the equestion then is it y=ox

Best ResponseYou've already chosen the best response.0remember x is a variable, and is allowed to take all values on the real line, but it obeys the law 0x=0

Best ResponseYou've already chosen the best response.1k how would you do this one ( 100,300 ) and (101,299 )

Best ResponseYou've already chosen the best response.0y_2y_1 = 299  (300) = 299 + 300 = 1 x_2  x_1 = 101  100 = 1 so it is 1/1 = 1. Your way worked too which is a good thing!

Best ResponseYou've already chosen the best response.1so what would the equestion bee y=1x+ ??

Callum29

Best ResponseYou've already chosen the best response.0use y=x+b and one of your coordinate pairs to solve the equation for b. (Gradient is 1 not 1 by the way).
