1. Answer: y=2x+1

   Step-by-step explanation:

   First, find the slope. 9+3/4+2=2, so m=2 (m stands for the slope in the slope-intercept form of y=mx+b)

   So we have y=2x+b

   Substitute one of the points into the equation to find b (the y-intercept)

   I’ll do (4,9) because it’s easier

   9=4×2+b

   9=8+b

   b=1

   So your final answer is y=2x+1

2. Answer: y= 2x + 1

   Step-by-step explanation:

   Slope–Intercept Form is y= mx+b

   To find the slope, we take the rise/run

   We see that y increased by 12 and x increased by 6, so our slope is

   12/6 = 2

   Our y-intercept is located at ( 0, 1)

   So our answer is y=2x + 1
