If a = t and b=2 then find the value of - 2ab and - 3a+b

Step-by-step explanation:

Given,

a=t

b=2

-2ab=-2×t×2 = -4t

-3a+b=-3×t+2= -3t+2

can someone answer this question plz

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
