Answer:
<em>z</em> = -3
Step-by-step explanation:
hopefully this helps! :)
X could be a variable to represent "the number"
x - 9 = 4x + 5
hope this somewhat helps, not sure if its correct!
How many people surveyed is just asking you how many people took the survey so count the total amount of tally marks you did
Since we have that the slope is m = 7/9 and the y-intercept is b = 12, we can write the equation of the line in slope-intercept form:

to find three coordinate points, we can use arbitrary values on x to get the y-coordinate. To make things easier, let's use x = 9, 18 and 27:

therefore, the line with slope m = 7/9 and y-intercept 12 passes through the three points (9,19), (18,26) and (27,33)
