Write an equation in slope intercept form (2,1) m=3

The equation is y = 3x - 6

Step-by-step explanation:

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = y intercept

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = (y2 - y1)

Change in value of x = (x2 -x1)

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

From the information given,

Slope, m = 3

The points given are (2,1)

y = 1

x =

y = mx + c

1 = 2×3 + c

c = 1-6 = -5

The equation is

y = 3x - 5

if x = 1, then the answer is 3.5
