For the linear function (x)=7x-2, which of the following is true?
1)it has a slope of 7 and a y-intercept of -2.
2)it has a slope of -2 and a y-intercept of 7.
3)it has a slope of 7x and a y-intercept of -2.
4)it has a slope of -2 and a y-intercept of 7x.

Correct option is : 1) It has a slope of 7 and a y-intercept of -2.

Step-by-step explanation:

The given function is :

                   .....1

The general form of equation of a linear function is given by :

                 .....2

where, y is the dependent variable, x is the independent variable, m is the slope of the function and c is the y-intercept.

On comparing equations 1 and 2, we get:

m = 7,c = -2

Thus, we can conclude that : Slope of equation is 7 and y-intercept is -2.

Thus, only option 1 satisfies the given solution.

what is the rest of the question? ?

55 degrees because 55+55=110 degrees
