Mars2501 [29]
Divide each term in 4m < -8 by 4.
4m/4 < -8/4
Then reduce the expression by cancelling the common factors. 
m < -8/4
Simplify the right side of the equation.
Divide 8 by 4 to get 2.
m < -1*2
Multiply -1 by 2 to get -2

Determine the intercepts of the line.
kifflom [539]

Answer:

x-intercept: (3, 0)

y-intercept: (0, -10)

Step-by-step explanation:

<u>X-intercept:</u>

We can see that the line crosses the x-axis at the 3. Let's imagine that this automatically makes a point. If the point is directly on the line, that means that the opposite coordinate (in this case, the y-coordinate) will be 0. This is because the point is directly at the 0 on the y-axis; it doesn't go up nor down.

<u>Y-intercept:</u>

The same goes for the opposite coordinate: if we picture a point at where the line intercepts the y-axis, there will be a point at -10 on the y-axis. Since the point is directly at 0 on the x-axis (meaning that it doesn't go left nor right) we know that the x-coordinate will be 0.
