-7

Put in this form. Y = mX + c3X - 7Y = 8- 7Y = - 3X + 8Y = (3/7)X - 8/7===========Y intercept = - 8/7-----------------------

y intercept 7 x intercept 7/3

-7/5 or -1.4

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.

If you mean: 7x-3y = 21 then y = 7/3x-7 whereas -7 is the y intercept and 7/3 is the slope

They are: 7/3 and -7 respectively
