What is the slope, m, and the y-intercept of the line that is graphed below? On a coordinate plane, a line goes through points (
salantis [7]

Answer:

m = 1; (0, 3) is the correct answer.

Step-by-step explanation:

The general equation of a line is given by:

y=mx+c

where, m is the slope of line

c is the y-intercept and

(x,y) are the points from where the line passes.

We are given that the line passes through 2 points (-3,0) and (0,3).

Putting the values of (x,y) in the equation of line.

Putting (0,3):

3 = m \times 0 + c\\\Rightarrow c =3

So, y-intercept is (0,3).

Hence, equation of line becomes:

y = mx + 3

Putting (-3,0) in y = mx + 3:

0 = m(-3) +3\\\Rightarrow 3m = 3\\\Rightarrow m =1

So, the equation of line becomes:

y = x +3

Please find attached graph.

m = 1; y intercept (0, 3) is the correct answer.
