Answer:
26. D
28. D
29. C
Step-by-step explanation:
27. y= (rise/run)x+b y=mx+b where b is y-intercept and m is slope or rise over run or y2-y1/x2-x1
So y=8/2+6 = y=4x+6, thus the answer is D
28. Polynomial Interpolation is a method of estimating the values between known data points, thus the answer is D
29. From graph inspection we have slope of 2 and crosses y-axis or has y-intercept of negative 3 or -3
So we have y=2x-3, thus the answer is C
