Question

Graph this function: y + 1 = 2(x + 3) Click to select points on the graph.

Answer 1

Answer:

use points (0,5) and (1,7)

see below for graph

Step-by-step explanation:

First, we'll turn the equation from point slope form (y-y1=m(x-x1)) into slope intercept form (y=mx+b)

y+1=2(x+3)

do the distributive property

y+1=2x+6

subtract 1 from both sides

y=2x+5

We'll need two points to graph the line.

You can subsitute x or y as any number you like and solve the equation.

For example:

if x=0:

y=2(0)+5

y=5

so the point would be (0,5)

and if x=1

y=2(1)+5

y=2+5

y=7

point: (1,7)

Use the points (0,5) and (1,7)
