Answer:
y=-4x-3
Step-by-step explanation:
Hi there!
We are given the following two points: (-2,5) and (-1,1)
We want to write the equation of the line that passes through these two lines in slope-intercept form 
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
First, let's find the slope
The formula for the slope (m) calculated from 2 points is  , where
, where  and
 and  are points
 are points
We have everything we need to calculate the slope, but let's label the value of the points to avoid any confusion 

Now substitute into the formula 
m=
m=
Simplify
m=
Subtract
m=
Divide
m=-4
Now substitute -4 as m into the equation: 
y=-4x+b
Now we need to find b
As the equation passes through both (-2, 5) and (-1, 1), we can use either point to help solve for b. 
Taking (-2,5) for example: 
Substitute -2 as x and 5 as y: 
5=-4(-2)+b
Multiply
5=8+b
Subtract 8 from both sides
-3=b
Substitute -3 as b. 
y=-4x-3
Hope this helps!
