Answer:
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
