Answer:
x - intercept: (3, 0)
y - intercept: (0, 9)
Step-by-step explanation:
This equation is written in standard form,
To find the intercepts it would be easier to put the equation in
slope-intercept form y = mx + b
- x and y are the variables
- m is slope, slope = rise / run
- b is the y - intercept, when x = 0
- the x - intercept is when y = 0
9x + 3y = 27
subtract 9x from both sides
(9x - 9x) + 3y = 27 - 9x
3y = 27 - 9x
Divided both sides by 3
3y / 3 = 27 - 9x / 3
y = 27 / 3 - 9x / 3
y = - 3x + 9
Now we can plug in x = 0, to find y - intercept:
y = - 3(0) + 9
y = 0 + 9
y = 9
Now we can plug in y = 0, to find x - intercept:
0 = - 3x + 9
0 - 9 = - 3x + 9 - 9
-9/3 = -3x/3
-3 = -x
3 = x
