Answer:
y = 3x + 3
Step-by-step explanation:
The slope intercept form is y = mx+b
M = slope
B = add on
To solve this problem, we must find to points on the line.
(1,6) and (2,9) are two possible points
x1 y1 x2 y2
To find the slope, we must do y2-y1/x2-x1
9-6/2-1 = 3/1
The slope, m, is 3
y= 3x + b
To find b, we need to plug in the numbers
(2,9)
9 = (2 * 3) + b
9 = 6+b
b= 3
The equation is y=3x+3
Hope this helps :)
