Answer:
6x -5y = 15
Explanation:
The given line has a slope of 1.5 and a y-intercept of 4. We assume that "translated down 7 units" means the y-intercept needs to be -3. "Less steep" will mean the slope is less than 1.5. We can make the slope be 1.2, so it will be less steep.
Then the slope-intercept form of the desired line is ...
y = 1.2x -3
Adding 3-y, this becomes ...
1.2x -y = 3
Multiplying this by 5 to put it into standard form, we have ...
6x -5y = 15

Additional comment
Since the lines have different slopes, each point on the original line will be translated up or down by a different amount. We chose the y-intercept as the point to be translated by the specified amount. The question could be more clear on that point, as well as whether lines with negative slope (say, -2) are considered to be "less steep."
