For the linear function (x)=7x-2, which of the following is true?
1 answer:
Answer:
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.
