What is how do I find m and b?

Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept → (0, b)
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
=====================================
From the table we have y-intercept (0, 5) → b = 5 and other point (1, 26).
Calculate the slope:
[tex]m=\dfrac{26-5}{1-0}=\dfrac{21}{1}=21[/tex]
