Question

Find slope
Both question 4 and 5 using simplest form.​

Answer 1

4.

Slope intercept form;

y = mx + b

y = independent variable

x = dependent variable

m = slope(rise/run)

b = y-intercept(where the line reaches the y-axis)

In this case, 4/7 is the slope, and -8/9 is the y-intercept.

So 4/7 is the slope.

5.

Slope intercept form;

y = mx + b

y = independent variable

x = dependent variable

m = slope(rise/run)

In the equation, we need to first format it into the formula shown above.

13x - 4y = 15

-13x -13x

-4y = -13x + 15

/-4 /-4

y = 13/4x + 14,

13/4 ← already in simplest form

So, 13/4 is the slope and 15 is the y-intercept.

Answer 2

4)

The slope of the line is the coefficient of x, when the line is in its simplest form (y=mx+b)

`m = (4)/(7)`

5)

We want to rewrite the second equation in its simple form first:

`13x - 4y = 15`

`- 4y = - 13x + 15`

`y = ( - 13)/( - 4) x + (15)/( - 4)`

`y = (13)/(4) x - (15)/(4)`

`= > m = ( 13)/(4)`
