Write an equation of each line in standard form with integer coefficients.<br> 4. y = 2.4x + 1.8

Nadusha1986 [10]

Answer:

Step-by-step explanation:

The standard form of an equation of a line:

$Ax+By=C$

We have

$4y=2.4x+1.8$

Convert

$4y=2.4x+1.8$ <em>multiply both sides by 10</em>

$40y=24x+18$ <em>subtract 24x from both sides</em>

$-24x+40y=18$ <em>change the signs</em>

$24x-40y=-18$ <em>divide both sides by 2</em>

$12x-20y=-9$

Problem 3

Murljashka [212]

Answer:

$-\frac{2}{5}$

Step-by-step explanation:

Given expression:

2x + 5y = -10

The equation of a straight line is;

y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

Now;

let us write the given expression in slope intercept format;

2x + 5y = -10

5y = -2x - 10

y = $-\frac{2x}{5}$ - 2

So, the slope of the line is $-\frac{2}{5}$
