Find an equation of the line passing through the given points. Use function notation to write the equation. ​(3​,8​) and ​(4​,13
Olegator [25]

Answer:

f(x)=5x-7

Step-by-step explanation:

The given line passes through the points;

(x_1,y_1)=(3,8)

and

(x_2,y_2)=(4,13)

Let us find the slope using;

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{13-8}{4-3}

m=\frac{5}{1}=5

The equation is given by;

y-y_1=m(x-x_1)

We substitute the values into the formula to obtain;

y-8=5(x-3)

y=5x-15+8

y=5x-7

There the equation of the line is

f(x)=5x-7
