Find the slope “m” and the y-intercept “b”. a. y = 3x − 4 b. 4x − 5y = 15

Mathematics

xenn [34]3 years ago

Step-by-step explanation:

Equation of a line is y = mx + b

where

m is the slope

b is the y intercept

<u>First question</u>

<h3>a.)</h3>

y = 3x - 4

Comparing with the general equation above

Slope / m = 3

The y intercept / b = - 4

<u>Second question</u>

<h3>b).</h3>

4x - 5y = 15

First we must write the equation in the general equation above by making y the subject

That's

5y = 4x - 15

Divide both sides by 5

That's

\frac{5y}{5}  =  \frac{4}{5} x -  \frac{15}{5}

We have

y =  \frac{4}{5} x - 3

Comparing with the general equation above

Slope = 4/5

Y intercept = - 3

Hope this helps you

The sum of 3 consecutive number multiples of 6 is 162 find thesse numbers
MAXImum [283]

let the numbers are x , x+1 ,x+2

∴ 6 [ x + (x+1) +(x+2) ] = 162

∴ x + (x+1) + (x+2) = 162/6 = 27

∴3x + 3 = 27

∴ 3x = 27 - 3 = 24

∴ x = 24/3 = 8

<u>So, the numbers are 8 , 9 , 10</u>
