If the question is to find the slope-intercept form of both lines, here's the answer:
Both lines pass through the point (-3,-4), so we can use these coordinates in both equations. The slope-intercept form is represented by y=mx+b, with m the slope, b the intersection of the line with Y'Y for x=0, y and x the coordinates of a point.
Let's first apply all these for the first line, with a slope of 4.
y = mx + b
y=-3; x=-4; m=4. All we need to do is find b.
-3 = 4(-4) + b
-3 = -16 + b
b=13
So the equation of the first line is y= 4x + 13.
Now, we'll do the same thing but for the second line:
y=-3; x=-4; m=-1/4, and we need to find b.
-3 = (-1/4)(-4) + b
-3 = 1 + b
b= -4
So the equation of the second line is y=(-1/4)x - 4
Hope this Helps! :)

Step-by-step explanation:
Answer:
360 = 2(2w+76)
Step-by-step explanation:
Answer:
x=-4, y=15
Step-by-step explanation:
3x+y=3
2x+y=7
Multiply top by -1
-3x-y=-3
2x+y=7
Add equations together
-x=4
x=-4
Plug x=-4 into any equation
3(-4)+y=3
-12+y=3
y=15
Answer:160 miles
Step-by-step explanation:
Since one inch is equal to 20 miles, multiply 8 by 20. 8*20 = 160
