4x (2x - 6)
8x - 24x
= -16x
For the first question, find the mean, first quartile, minimum, maximum, and third quartile, and then graph on the x-axis (a number line). Then, create a line through the median, first, and third quartile. Lastly, connect the median, first and third quartile to make a box. Google images for more details.
The standard form:
The slope-intercept form:
m - slope
b - y-intercept (0, b).
We have the point (0, 43) → b= 43.
Next point (2, 55). Substitute to the slope formula:
Therefore we have:
<em>subtract 6x from both sides</em>
Find common denominators and move from there
