x intercept is -3 and y intercept is 9
Solution:
Given equation of line is:
y = 3x + 9
Find the x intercept:
Substitute y = 0 in given
0 = 3x + 9
3x = -9
Divide both sides by 3
x = -3
Thus x intercept is -3
Find the y intercept:
Substitute x = 0 in given
y = 3(0) + 9
y = 0 + 9
y = 9
Thus the y intercept is 9
