Which is an equation in point-slope form of the line that passes through the points (7, 5) and (–4, –1)?

Answer:

[tex]y-5=\frac{4}{11} (x-7)[/tex]

Step-by-step explanation:

We start by first finding the slope by using the slope formula:

[tex]m= \frac{y_{2}-y_{1}  }{y_{1}-y_{2}  }[/tex]

If we let (7,5) → [tex](x_{1} , y_{1} )[/tex] and (-4,1) → [tex](x_{2} , y_{2} )[/tex] then:

[tex]m = \frac{1-5}{-4-7} = -\frac{4}{-11} =\frac{4}{11}[/tex]

Now that we have the slope, we can find the equation of the line in point-slope formula:

[tex]y-y_{1} = m(x-x_{1} )[/tex]

where m is the slope and [tex]x_{1}[/tex] and [tex]y_{1}[/tex] is a coordinate on the line. I will use the point: (7,5)

The equation in point-slope form is then:

[tex]y-5 = \frac{4}{11} (x-7)[/tex]
