What is the equation of the line that contains the two points (0,-1) and (-1, -3)?

Step-by-step explanation:

y=2x-1.

Use the formula y2-y1 over x2-x1. Plug in your digits. (0,-1) and (-1,-3). So you put in -1-0 and get -1 as x. For y plug in -3-(-1) and get 2 as x. A formula for a slope intercept is y=mx+b. So y=2x-1.

7. apply maths to real world problems.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
