Answer:

y = -1/4x - 1

Step-by-step explanation:

The equation of a line is y = slope*x + y-intercept

Find the slope by picking two points shown on the graph and doing (y1-y2)/(x1-x2): (4, -2) & (-8, 1) = (-2-1)/(4-(-8) = -3/12 = -1/4 so the slope is 4.

Find the y-intercept by seeing where the line crosses the y-axis: y= -1

So therefore, y = -1/4x - 1

How do I solve for n and m using special right triangle rules.

kenny6666 [7]

Answer:

Because the triangle is a 45-45-90 triangle, the n and m should be the same lengths. For these types of triangles, the hypotenuse is $x\sqrt{2}$ and the side lengths are x. Because we are given the length of the hypotenuse, we need to find the x-value. The equation should be 6= $x\sqrt{2}$ . Simplify to get x= $3\sqrt{2}$ . So, the length of n and m should both be $3\sqrt{2}$ .
