Question

(-2,-5) and (8,-3) using slope intercept form, write an equation of the line through each pair of points ​

Answer 1

Answer:

Step-by-step explanation:

Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b. ...

Point-slope form = y − y 1 = m ( x − x 1 ) , where ( x 1 , y 1 ) is the point given and m is the slope given.

Answer 2

Answer: y = 1/9x - 3 8/9

Step-by-step explanation:

To find the slope, you must do y2-y1/x2-x1

-3+5/8+10

2/18

1/9 is the slope.

Then, you put the slope into slope-intercept form and take one of the coordinates and add it into the equation. Let's do the second coordinate.

slope-intercept form is y=mx+b

y=mx+b

-3 = 1/9(8) + b

-3 =  8/9 +b

-3 8/9 = b

y = 1/9x - 3 8/9

Hope this helps!
