​​1. Find the slope of the line

​

Multiple Choice

Which is the point-slope form of a linear equation?

• $$y=mx+b$$  

• $$y-y₁=m\left(x-x₁\right)$$  

• $$Ax+By=C$$  

• $$ax^2+bx+c=0$$  

Multiple Choice

Which of the following equations correctly represent the equation of the line in point-slope form?

• $$y+1=\frac{1}{2}\left(x-5\right)$$  

• $$y+1=-\frac{1}{2}\left(x-5\right)$$  

• $$y=-\frac{1}{2}x+\frac{3}{2}$$  

• $$y-5=\frac{1}{2}\left(x+1\right)$$  

Fill in the Blank

Fill in the Blank

Write the equation of the line that has the following features:

$$m=6$$  and goes through point $$\left(4,\ -5\right)$$

Multiple Select

Which of the following is the equation of the line that goes through the following points? Select two that are correct.

$$\left(4,\ 7\right)\ and\ \left(5,\ 1\right)$$  

Hint: Find slope first using the slope formula.

Then write the equation using each point.

• $$y-1=-6\left(x-5\right)$$  

• $$y-7=-6\left(x-4\right)$$  

• $$y-7=6\left(x-4\right)$$  

• $$y-1=6\left(x-5\right)$$
