Write the slope-intercept form of the line that passes through (-10,17) and (5,-4)

luda_lava [24]

Answer:

y = 7/5 x + 31

Step-by-step explanation:

To find the slope, we need to use the formula

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

m =(-4-17)/(5- -10)

= -21/(5+10)

= 21/15

Divide the top and bottom by 3.

= 7/5

The slope is 7/5.

Using the point slope form of the equation,

y-y1 = m(x-x1)

y-17 = 7/5 (x--10)

y-17 = 7/5(x+10)

Distribute the 7/5 ths.

y-17 = 7/5 x + 7/5*10

y-17 = 7/5 x +14

Add 17 to each side

y = 7/5 x + 14 + 17

y = 7/5 x + 31

This is in slope intercept form, with the slope being 7/5 and the y intercept of 31

Julia is going for a walk through the neighborhood. What unit of measure is most appropriate to describe the distance she walks?

Kryger [21]

Answer:

Possibly meters or feet/yards.

A walk through a neighborhood would be less than a mile/kilometer but much further than an inch/centimeter.

The manager of a restaurant found that the cost to produce 200 cups of coffee is $65.00 , while the cost to produce 250 cups i

PIT_PIT [208]

Answer:

a). y = 0.25x + 15

b). x = 480 cups

Step-by-step explanation:

(a). Let the equation of the linear function passing through a point (x', y') is,

y - y' = m(x - x')

'm' = slope of the line

b = y-intercept

Two points lying on the linear function will be (200, 65) and (250, 77.5).

Slope of the line 'm' = $\frac{y_2-y_1}{x_2-x_1}$

m = $\frac{77.5-65}{250-200}$

= $\frac{12.5}{50}$

= 0.25

Therefore, equation of the line passing through (200, 65) and slope 0.25 will be,

y - 65 = 0.25(x - 200)

y - 65 = 0.25x - 50

y = 0.25x + 15

(b). For y = $135 we have to calculate the number of cups of coffee produced.

135 = 0.25x + 15

0.25x = 135 - 15

0.25x = 120

x = 480 cups

Therefore, 480 cups of coffee will be produced.
