Answer:

[tex]y=-\frac{3}{4}x-\frac{3}{2}[/tex]

or

[tex]y=-0.75x-1.5[/tex]

Step-by-step explanation:

step 1

Find the equation of the line in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=-\frac{3}{4} \\point\ (-6,3)[/tex]

substitute

[tex]y-3=-\frac{3}{4}(x+6)[/tex]

step 2

Convert to slope intercept form

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

we have

[tex]y-3=-\frac{3}{4}(x+6)[/tex]

Isolate the variable y

[tex]y-3=-\frac{3}{4}x-\frac{9}{2}[/tex]

[tex]y=-\frac{3}{4}x-\frac{9}{2}+3[/tex]

[tex]y=-\frac{3}{4}x-\frac{3}{2}[/tex]
