Determine the value of x for which r | s if
• mz1 = 40 - 4x; and
• m 2 = 50 - 8x.

answer:

lol not sure about that sorry

Step-by-step explanation:

Slope-intercept form is y = mx + b

"m" is the slope, how steep the line is.

"b" is the y-intercept, where to graph hits the y-axis.

Check the scale for this grid. Since there are "1" written on the first box after the middle, one square = one unit.

To find "m", use     between the two dotted points on the graph. The first point is always on the left.

"Rise" means how many squares above the first point the second point is.

Since the second point is below the first point, the number is negative.

"Run" means how many squares to the right the second point is.

To find "b", look at where the graph it touching the y-axis.

The y-axis is the vertical line (going from top to bottom).

Count the number of squares from the grid's middle to the graph line.

There are 3 squares.

Since the graph touches below the origin, this is a negative number.

b = -3

In the boxes, you put negative two (-2) and negative three (-3).

* Usually we would simplify the equation to y = -2x - 3.
