What is |-2.24|?

a. -224
b. -2.24
c. 2.24
d. 224

You should answer the homework yourself from my explanation.

Step-by-step explanation:

General equation of a line is

Y = mx + C ; m- slope or gradient C or b is that Value of Y in the expression when x= 0

Hence slope is y2 - y1/ x2-x1

From (x1, y1) and (x2,y2) ; we have :

x1=-1

y1=-5

x2=0

y2= 3

So slope is 3 - (-5)/0-(-1)= 3 + 5 / 1 = 8

so you know b already because it's the value of y when x = 0.

You can work the rest

Just substitute slope and the value of b, you would get the equation
