HELP ME PLEASE what are the x and y intercepts of the following line? -3x-2y=20

a) (-3/2,0), (0,-10)

b) (-20/3, 0), (0,-10)

c) (-3,2), (0,0)

d) (-3,0), (0,-2)

a) (-3/2,0), (0,-10)

Step-by-step explanation:

y = mx + b

Change the equation to y intercept form.

-3x - 2y = 20

Isolate -2y by adding 3x on both sides.

-2y = 3x +20

Divide everything by -2

y = - 10

If you have a ti 84 plus calculator put it in the calculator:

go to y =

then press 2nd graph

then press graph

you will be at the (x,y) table  

look at what (x,y) value match your choices.

Another way to solve this equation is to substitute.

a) is the correct choice

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
