3x + y = -1 y = -3x - 1 The graph is a straight line, with a slope of -3, passing through the point Y = -1 on the y-axis.
The starting point on the y-axis changes from -2 to 6.
3x + y = 7 First, turn the equation into the slope-intercept form, y = mx + b, where m is the slope of the graph that that equation represents (solve for y).3x + y = 7 subtract 3x to both sidesy = -3x + 7So you clearly see that the slope is -3.
y-3x-3 y=3x+3 A line with a slope of 3 crossing the y-axis at 3.
The graph of [ y = -3x ] is a straight line, through the origin, with slope of -3 .

3x - 9y = 27-9y = -3x + 279y = 3x - 27y = x/3 - 3The graph is a straight line, with (slope = 3), and passing through the point (y = - 3) on the y-axis.
3x + y = 7 First, turn the equation into the slope-intercept form, y = mx + b, where m is the slope of the graph that that equation represents (solve for y).3x + y = 7 subtract 3x to both sidesy = -3x + 7So you clearly see that the slope is -3.
y-3x-3 y=3x+3 A line with a slope of 3 crossing the y-axis at 3.
If a graph is a function, it will always have y=... or x=... (or anoher letter equals an equation) for example y= 3x-12 is a function
y = 3x =3(6) = 18 ... the ordered pair is (x,y) = (6,18)
