Write an equivalent expression for 7x + 4x + 3-1

We are given this expression:

Now we will use concept of like terms here:

like terms are terms that have the same variables and powers.

Now in our expression 7x and 4x are like terms.

So on adding 7x and 4x we get 11x.

Also we have 3 and -1 like terms.

Combining 3 -1 , we have 2.

So answer is 11x +2 .

i think 1: 2

step-by-step explanation:

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
