Question

99 POINTS What is the equation of the line graphed?

Answer 1

Answer:

y = 3x-2

Step-by-step explanation:

We have the y intercept  (where it crosses the y axis)

It crosses at y=-2

(0,-2)  We need another point to find the slope.

Another point is (1,1)

The formula for slope is

m=(y2-y1)/ (x2-x1)

We have 2 points (0,-2) and (1,1)

   = (1--2)/(1-0)

   = (1+2)/(1-0)

    3/1

m=3

The slope is 3 and the y intercept is -2

We can use the slope intercept form of the equation

y= mx+b where m is the slope and b is the y intercept

y = 3x-2

Answer 2

Answer:

y = 3x - 2

Step-by-step explanation:

Two of the coordinates are (2, 4) and (1, 1). The slope of these is 3/1, or 3. Plug this back in to get that the slope-intercept form is y = 3x - 2.
