Answer:

The equation in point-slope form of the line is:

y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)

Step-by-step explanation:

Given the points

  • (-1, -5)
  • (3, 2)

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(-1,\:-5\right),\:\left(x_2,\:y_2\right)=\left(3,\:2\right)

m=\frac{2-\left(-5\right)}{3-\left(-1\right)}

m=\frac{7}{4}

As the point-slope form is defined as

y-y_1=m\left(x-x_1\right)

where m is the slope.

substituting the values m=7/4 and the first point (-1, -5)

y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)

Therefore, the equation in point-slope form of the line is:

y-\left(-5\right)=\frac{7}{4}\left(x-\left(-1\right)\right)
