Question

Write a rule for the linear function with the following description: the graph has slope 2 and contains the point (-11).

A. y = 2x + 3
B. y = x + 1
C. y = 2x - 1
D. y = -x + 2

Answer 1

Option A: y = 2x+3 is the right answer

Step-by-step explanation:

Given

slope = m = 2

Graph contains (-1,1)

The graph of a linear function can be written by using the slope-intercept form of equation given by:

$y = mx+b$

Where

m is the slope and b is the y-intercept

So,

Putting the value of m

$y = 2x+b$

To find the value of b, putting the point (-1,1) in the equation

$1 = 2(-1) +b\\1 = -2 +b\\b = 1+2\\b = 3$

So the equation will be:

$y = 2x+3$

Hence,

Option A: y = 2x+3 is the right answer
