Answer:
y = - x-1
Step-by-step explanation:
We can find the equation of a line by using the slope/intercept formula: y=mx+c, where m is the slope and c is the y-intercept.
The y-intercept, c, is the y-value when the line crosses the y-axis. From the graph, we can see that this is -1.
The slope can be found by taking two points frown the line, (x,y) and (X,Y), and using the formula (Y-y)/(X-x). Two points on our line are (-4,0) and (0,-1):
Slope = (-1-0)/(0-(-4))
= -1/4
Now that we know the y-intercept (c) and slope (m), we can write our equation:
y=mx+c
y = - x-1

Answer:
K(3,2).
Step-by-step explanation:
We want to find a point K(x,y).
JK = 3/5 JL.
This means that:
We use this to find both the x-coordinate and the y-coordinate of K.
x-coordinate:
x-coordinate of J: -3
x-coordinate of L: 7
y-coordinate:
y-coordinate of J: -4
y-coordinate of L: 6
The point is K(3,2).
