Answer:
The x and y intercepts for y = 3x + 9 are:
y-intercept: 9
x-intercept: -3
Explanation:
I only see one equation: y = 3x + 9
This is in the slope-intercept format of y=mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).
This means the y-intercept is 9. When x = o, y = 9.
The x-intercept is the point the line crosses the x avis, so y = 0. Use y = 0 in the equation and calculate the value of x:
y=3x+9
0=3x+9
3x= -9
x = -3
