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 sides
y = -3x + 7
So you clearly see that the slope is -3.

what is a slope
y=3x+(3/2), so the slope is 3 or (3/1).
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.
y = 3x + 6slope = 3
3x+4y = 8 4y = -3x+8 y = -3/4x+2 in slope intercrpt form It has a negative slope so the straight line goes 'downhill'
