Question

I dont know this. plz help ​

Answer 1

y = x + 3

Explanation:

The given graph indicates that the y-intercept of this line is 3 (that is, b = 3). The y-intercept is also represented by (0, 3). The graph also goes through (-3, 0). The 'run' is the jump of the x-coordinate from -3 to 0, and thus is 3; the 'rise' is the jump of the y-coordinate from 0 to 3, and is thus 3. Therefore, the slope of this line, m, is rise/run, which here is m = 3/3, or just 1.

The slope-intercept equation y = mx + b is therefore y = x + 3.

I would suggest you write out your objective before attempting problem solution. In this case, write out "find the equation of the line shown in this graph, in slope-intercept form."

Answer 2

`\huge \colorbox{red}{y = x + 3}`

Explanation:

to understand this

you need to know about:

• linear equation
• PEMDAS

given:

• b=3

let's solve:

linear equation slope intercept form:

• 
  `y = mx + b`

m is 1 in this question

therefore

substitute the value of m and b

• y=x+3
