Answer:

y = 3x + 3

Step-by-step explanation:

y = mx + b where m= slope and b= y-intercept

the y-intercept is the point where x=0 or where the line crosses the y-axis.

This happens at (0,3) on the graph, so the y-intercept, or b, is equal to 3.

for m, slope can be defined as rise/run. So starting from a point you are given on the graph (-1,-2), count the number of spaces up you rise and how many you must go over (run) to get to the next point (0,3)

if you count, you should rise from (-1,-2) 5 spaces and move to the right (run) 1 space to get to (0,3).

rise/run = 3/1

3/1 = 3

the slope is 3.

now that you have the slope and the y-intercept, you can just plug it into the equation

y = 3x + 3

Answer:

Step 1 is incorrect.

Step-by-step explanation:

The given expression is :

$\dfrac{5}{2}-3x-5+4x=\dfrac{-7}{4}$

In step 1, Deepak rearranged the terms in order to simplify like terms together that is followed in step 2.

o, rearranging of the terms of an expression is commutative property and not distributive property. The distributive property is generally applicable to multiplication and is given as:

$x(y+z)=xy+yz$
