Answer:
- [tex]\boxed{\sf{y=-9}}[/tex]
Step-by-step explanation:
The slope-intercept form is the only way to solve this problem.
Slope-intercept form:
[tex]\rightarrow \sf{y=mx+b}[/tex]
- The m represents the slope.
- The b represents the y-intercept.
Using the slope is another way to solve.
(1,-9) and (-3,-9)
Use a slope formula.
Slope:
[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{rise}{run} }[/tex]
y2= (-9)
y1= (-9)
x2= (-3)
x1= (1)
Rewrite the problem.
[tex]\sf{\dfrac{(-9)-(-9)}{(-3)-1}=\dfrac{0}{-4}=\boxed{\sf{0} }[/tex]
- Therefore, the slope is 0.
We're not done yet.
y-intercept= (-9).
The m represents is 0.
The b represents is (-9).
- So, the correct answer is y=-9.
