C) $m=-1, y=7$

To find the slope and y-intercept, we need to rewrite the equation in slope-intercept form, which is y = mx + b.

x + y = 7

y = -x + 7

Therefore, the slope is -1 and the y-intercept is 7.

To graph the line, we can use the y-intercept to plot a point on the y-axis and then use the slope to find additional points.

Starting at (0, 7), which is on the y-axis, we can move down 1 unit (since the slope is -1) and right 1 unit to get to (1, 6), which is another point on the line. We can repeat this to find other points and then connect them to draw the line.

The graph should look like a diagonal line that goes from the top left to the bottom right of the coordinate plane.
