Describe how you would graph this line using the slope-intercept method. be sure to write in complete sentences. -(2/3)x + 490

The slope-intercept form is: y = mx + b  (m is the slope, b is the y-intercept [where x = 0 or (0 , y)])

Based on the equation, the y-intercept is 490, or (0, 490)

The slope is -2/3x

How slopes work >  [when you have a negative slope(-2/3x), you move down 2 units and to the right 3 units. when the slope is positive(pretend -2/3x is 2/3x), you move up 2 units, and to the right 3 units. The numerator tells you how many units you need to move to (-)down or (+)up, the denominator tells you how many units you need to move to the right]

To graph this line, I would start at the point (0, 490) or the y-intercept, then from that point I would begin using the slope to go down 2 units, and to the right 3 units to get a few points, such as (3, 488) and (6, 486)etc, and then draw a line through the points (hope this was helpful)

y=mx+b slope intercept form

m=slope

b=y-intercept

equation given;

y=(-2/3)x+490

So this tells us the graphed equation will have a decreasing slope of 2/3, so for every unit distance the line rises by 2 and runs by 3 units, and the line will cross the y-axis at (0,490) so now we just need to find where it crosses the x-axis then we can graph it easily. Substitute in the value of 0 for y into the given equation and solve for x. We get x=735 so that tells us at point (735,0) the line crosses the x-axis.

Any questions please feel free to ask. Thanks!

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.

step-by-step explanation:

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
