How do I find the slope if a line when y=4x+5

DaniilM [7]

Answer:

slope =4

Step-by-step explanation:

The slope intercept equation of a line is written in the form

y= mx+b

where m is the slope and b is the y intercept.

Since y =4x+5 is written is this form, we can see that 4 is the slope and 5 is the y intercept

What is the value of x?

Dafna1 [17]

Answer:

$3x = 12x - 81$ (vertically opposite angles)

$→3x - 12x = - 81$

$→- 9x = - 81$

$→x = \frac{ - 81}{ - 9}$

$→x = \frac{81}{9}$

$→x = 9$
