In this question, you're trying to find the slope of the equation.
In order to find the slope, you must make the equation in to slope-intercept form.
Slope-intercept form:
y = mx + b
Turn the equation into slope-intercept form:
y - 3x=19
Add 3x to both sides
y = 3x + 19
Now it's in slope-intercept form ,the slope is represented with the "x" variable.
Therefore, your slope would be 3.
Answer:
Your slope is 3
