The slope-intercept form:
y = mx + b
m - a slope
b - a y-intercept
The slope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
10.
b = 1
[tex](0,\ 1),\ (2,\ 3)\\\\m=\dfrac{3-1}{2-0}=\dfrac{2}{2}=1[/tex]
Answer: y = x + 1
11.
b = 6
[tex](0,\ 6),\ (1,\ 4)\\\\m=\dfrac{6-4}{0-1}=\dfrac{2}{-1}=-2[/tex]
Answer: y = -2x + 6
