Yolanda pay would increase by $20 for each hour worked. The slope of the line is 20.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
The standard form of a linear equation is:
y = mx + b
Where m is the slope of the line and b is the initial value.
Let y represent the pay after x hours. The line passes through (0, 30) and (3, 90), hence:
slope = (90 - 30) / (3 - 0) = 20
