Answer:

The equation in the slope-intercept form will be:

Step-by-step explanation:

Given the points

  • (8, -4) and (-2, 5)

The slope between two points

[tex]m=\frac{5-\left(-4\right)}{-2-8}[/tex]

[tex]m=-\frac{9}{10}[/tex]

As the point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = -9/10 and (8, -4)

[tex]y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)[/tex]

Writing the line equation in the slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope and b is the y-intercept

so the equation in the slope-intercept form will be:

[tex]y-\left(-4\right)=-\frac{9}{10}\left(x-8\right)[/tex]

[tex]y+4=-\frac{9}{10}\left(x-8\right)[/tex]

subtract 4 from both sides

[tex]y+4-4=-\frac{9}{10}\left(x-8\right)-4[/tex]

[tex]y=-\frac{9}{10}x+\frac{16}{5}[/tex]

Therefore, the equation in the slope-intercept form will be:

[tex]y=-\frac{9}{10}x+\frac{16}{5}[/tex]
