The answer is in point slope form.

2x-y-1=0

Explanation:

(y-y_1)=m(x-x_1)

(y-(-5))=2(x-(-2))

y=2x-(-4)+(-5)

y=2x-1

2x-y-1=0

y=2x-1

Explanation:

"the equation of a line in "color(blue)"slope-intercept form" is.

•color(white)(x)y=mx+b

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

"here "m=2

rArry=2x+blarrcolor(blue)"is the partial equation"

"to find b substitute "(-2,-5)
"into the partial equation"

-5=-4+brArrb=-5+4=-1

rArry=2x-1larrcolor(red)"in slope-intercept form"
