Answer:

the slope is 1/2

Step-by-step explanation:

pick two points to find the slope, i chose (2,1) and (0,0)

m = (y2 - y1) / (x2 - x1)

m = (1-0) / (2-0)

m = 1/2

Tamika’s father gave her $50 to start her savings account. She deposited $15 in the account each month that followed. Is the amo
gtnhenbr [62]

Answer:

B

Step-by-step explanation:

The origin means it starts at 0 but because she was given $50 she starts at 50 and increases  - this rules out A or C

The fact that she is putting 15 each month means that she will surpass the original $50 in more than 3 months . This means that it is B ( in my opinion)

PLZ HELP MEEEE 40 POINTS!
ASHA 777 [7]

Step-by-step explanation:

We have been given that Jeanie stated that the equation of this line best fit for the scatter plot is y=\frac{1}{2}x+8.

Let us find the slope of the line of best fit using points (2,7) and (4,6) in slope formula.

\text{Slope}=\frac{y_2-y_1}{x_2-x_1}

\text{Slope of line of best fit}=\frac{6-7}{4-2}

\text{Slope of line of best fit}=\frac{-1}{2}

We can see that slope of line of best fit is -\frac{1}{2}.

Since the equation of a line written in slope-intercept is in form: y=mx+b, where m=slope of line, b= y-intercept.  

Upon substituting m=-\frac{1}{2} and coordinates of one point in slope-intercept form of equation we will  get,

6=-\frac{1}{2}\times 4+b

6=-2+b

6+2=-2+2+b

8=b

Upon substituting m=-\frac{1}{2} and b=8 in slope intercept form, we will get,

y=-\frac{1}{2}x+8

We can see that equation of the line of best fit is y=-\frac{1}{2}x+8. Jeanie got 1/2 as slope of the line of best fit, which is wrong, therefore, Jeanie's equation of the line of best fit is not correct.
