Answer:
Explanation:
I will be using the equation
for this explanation.
Graph 1:
- The equation for the positive slope is
. The positive slope (m) has a slope of positive 1 (x), and intersects the y-axis at -1, creating the equation
.
- The equation for the negative slope is
. If you look, the first point is at (0,-3) with the next point being (1,0), which shows that the slope has a negative slope (m) of 3. The negative slope intersects at (0,3), giving us the b variable in the equation. Putting these values into the equation, we get
.
Graph 2:
- The steeper of the two functions will have the equation
. The function has a positive slope (m) of
, or simply 2, and intersects the y-axis (b) at (0,-4). Put these variables into the equation
, and you get
.
- The lower function will have the equation
. For every 1 square, the line moves up, it takes 2 squares to the right to get to the next point, which gives us the variable m of
. This function intersects the y-axis at (0,2), which gives the variable b of +2.
