Answer :
To find the slope of a line given an equation in the form of ax + by = c .The slope of 7x + y = -4 is 7.
To find the slope of a line given an equation in the form of ax + by = c, you first need to put the equation into slope-intercept form, which is y = mx + b. To do this, start by subtracting ax from both sides of the equation, leaving you with by = c - ax. Then divide both sides by b, giving you y = (c - ax) / b. This is the equation in slope-intercept form, with m being the slope, which in this case is 7.
