When a point lies on the x-axis, its y- coordinate is 0. The same is true for the reverse. So if your point lies on the y-axis, its x coordinate will be 0.

Find the slope of the line that passes through (4, 9) and (1, 4).
alexandr1967 [171]

We can use the points (1, 4) and (4, 9) to solve.

Slope formula: y2-y1/x2-x1

= 9-4/4-1

= 5/3 or 1 2/3

Best of Luck!

Billy the friendly Robot uses 50 N of force to lift a box 2 meters in the air. How much work did Billy perform?
padilas [110]

Answer:

0.04

Step-by-step explanation:

Set it up like this: 50N=2.

you want to leave "N" by itself on one side of the equal sign so divide 50N by 50 and your are left with "N". You also have to divide 50 by 2 on the other side of the equal sign. now you have N=2÷50.

2÷50= 0.04!

1. What is the slope of the line passing through (-2,3) and (4, -5)?
olganol [36]

Answer:

Step-by-step explanation:

hello :

1) Hello :

let  A(-2,3)    B(4,-5)

the slope is :   (YB - YA)/(XB -XA)

(-5-3)/(4+2)  =  -8/6 =-4/3

2) Use the point-slope formula.

y - y_1 = m(x - x_1)    you have :

m=0      x_1=4        y_1=6

an equation for this line is : y-6 =0(x-4)

so : y=6

Total cost = cost of paper clips + cost of index cards
Total cost = cost of one box of paper clips * number of boxes + cost of one box of index cards * number of boxes
55.40=15p+7i \\ 61.70=12p+10i \\ \\ 61.70-12p=10i \\ i = \frac{61.70-12p}{10} \\ i=6.17- \frac{6p}{5} \\\\ 55.40=15p+7(6.17- \frac{6p}{5})\\55.40=15p+43.19-\frac{42p}{5}\\55.40=15p-8.4p+43.19\\12.21=6.6p\\p=1.85 \\\\55.40=15(1.85) +7i\\55.40=27.75+7i\\7i=27.65\\i=3.95
So your answers are:
p = $1.85
i = $3.95
