Answer:
The slope is 0 and it's undefined.
Explanation:
To find the slope, first you have to solve these problems from left to right. Then, you'd use the slope formula of
.
![\displaystyle y_2=3\\\\\displaystyle y_1=3\\\\\displaystyle x_2=5\\\\\displaystyle x_1=(-4)\\](https://img.qammunity.org/2020/formulas/mathematics/high-school/7ijo6t021jjnsuuw6l9z0mqx732rposw7v.png)
Next, you had to solve.
![\displaystyle(3-3)/(5-(-4))=(0)/(9)=\large\boxed{0}](https://img.qammunity.org/2020/formulas/mathematics/high-school/tlfv2y5gl15v23c8ho23kmaf3nz5j4l14w.png)
As a result, the slope of the line through (-4,3) and (5,3) is undefined.
I hope this helps you!
Have a wonderful blessing day!
Good Luck!
