The slope-intercept form:

$y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}$

m - slope

b - y-intercept → (0, b)

We have the points (-9, -9) and (0, 1) - y-intercept → b = 1.

Calculate the slope:

$m=\dfrac{1-(-9)}{0-(-9)}=\dfrac{10}{9}$

Answer: $y=\dfrac{10}{9}x+1$

11111nata11111 [884]

5 and above give it a shove, 4 and below let it go
So if the number in the tenths spot it 5 and above you round up, if it is 4 and below you take the whole number in the original number used and that is your answer. In this case the tenth spot is 5 so you round it to 90
