Question

Help plsssssssss??????

Answer 1

y= -1/3x-3

Explanation:

The slope is -1/3 because the equation is rise/run. The rise is 1, and the run, or horizontal length, is 3. Because the line is slanting toward the left, the slope will be negative.

y=mx+b is the equation for a linear line.

y= -1/3x+b (substitute the slope in)

choose any point on the line, for example, (0,-3).

-3= -1/3(0)+b (0 is the x, and -3 is the y)

b= -3

Your equation will be y= -1/3x-3

Answer:

y = -1/4x -3

Explanation:

The slope is found by counting grid squares between grid crossing points. The line crosses grid points at (0, -3) and again at (4, -4). That is, for 4 units to the right, it drops 1 unit, so the slope is ...

m = rise/run = -1/4

The crossing at (0, -3) tells you the y-intercept is b = -3, so the slope-intercept equation is ...

y = mx +b

y = -1/4x -3
