Find the slope and Y_intercept of the line 3x+y-9=0
2 answers:
Answer:
slope: -3
y-intercept: 9
Step-by-step explanation:
To find the slope and y-intercept, we can manipulate the equation to slope-intercept form. Slope-intercept form is y=mx+b where m is slope and b is y-intercept.
[subtract both sides by 3x]
[add both sides by 9]
Now, our equation is in slope-intercept form. We can see that the slope is -3 and the y-intercept is 9.
