Question 394014
in the eqation
Y = MX + B
M is the slope, and B is the Y-Intercep (Y when X is 0)

m=1 b(0,7)

m=1 means the slope is 1
(0,7) means the y intercept is 7
the equation would be 
Y = X + 7

m=-4 b(0,2)

m = -4 means the slope is -4
(0,2) means the y intercept is 2
the equation would be
Y = -4X + 2


you should know how to graph them in standard form then
