What is the equation of a line that passes through point r(−4, −3) and has a slope of 7?

1 answer:

5 0

Slope m= 7
From general equation of a line;
y=mx+c
y=7x+c

Finding value of c by replacing for;
y=-3
x=-4
-3=7*(-4)+c
-3=-28+c
c=25
y=7x+25

Answer:

a cube that is 1 yard long, 1 yard wide, and 1 yard high

Step-by-step explanation:

The dimensions for a unit cube are:

$1\times1\times1$

<u>Please note that the units for each side MUST be the same (or if they're different, then the lengths have to be equivalent). </u>

<u />

Looking at the answer choices, we can see that the last answer choice is a 1 yd by 1 yd by 1 yd cube, therefore it is a unit cube.

X=16 because the the small triangle you just multiply the big triangle by 4

Hello there! you can use the expression $\frac{ y_{1}-y_{2}}{x_{1}-x_{2} }$ !

To find slope, subtract the y values over the x values.

In this case:

2 - - 1 / - 3 - 7

3 / -10

So, -3/10 would be the slope of these points.

Hope this helps, have a great day!

7800 because it grows 300 per 2 hours so 3000 + 4800 = 7800
