To find the y-intercept, we first need to convert the given equation into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
3x + 3y = -7
3y = -3x - 7
y = -x - 7/3
The y-intercept is the value of y when x = 0. Substituting x = 0 into the equation, we get:
y = -0 - 7/3
y = -7/3
So, the y-intercept is -7/3.
The coefficient in front of x in the slope-intercept form is the slope, so the slope of the line is -1.
Therefore, the y-intercept is -7/3 and the slope is -1.
Find the y-intercept and the slope of the line.
