Answer:

blue piece is 1/2 because it takes up half of the square, the purple is only 1/4 because it would take 4 purple to fill the big square and the orange is half of the purple so it takes double of pieces so 8 pieces which is 1/8

Write the equation of the line parallel to y=3x-2 that passes through (3, 2) in point-slope form

AleksandrR [38]

Substitute the x and y values from (3,2).

Formula: y=mx+b

2= 3(3)+b
2-9= -7

y=3x-7

Calculate the slope of the line given the points (2,1) and (1,-4)

Dmitrij [34]

The equation for the slope of a line is:

y2-y1/x2-x1

So:

-4-1/1-2 = -5/-1 =5

The slope of the line is 5.

Find the equation for the trend line through the points (0, 11) and (100, 33). Then use it to predict the number of baskets Romy

sleet_krkn [62]

Answer:

28 baskets

Step-by-step explanation:

The equation for a linear trend line is given by:

y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y when x is zero).

The equation of a line passing through two points $(x_1,y_1)\ and\ (x_2,y_2)$ is:

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

y represent the number of baskets made and x represents the time take. Given that the line passes through the points (0, 11) and (100, 33), hence:

$y-11=\frac{33-11}{100-0}(x-0)\\\\y-11=\frac{11}{50}x\\\\y= \frac{11}{50}x+11$

The number of baskets Romy would make after practicing for 80 minutes (x = 80) is:

$y=\frac{11}{50}x+11\\\\y=\frac{11}{50}(80)+11 \\\\y=17.6+11\\\\y=28.6\\\\Therefore\ y\ =\ 28\ baskets$
