Answer: Yes
Step-by-step explanation: A linear equation is an equation which represents a line. A linear equation has a variable that is raised to the 1st power.
Linear equations can be written in the form y = mx + b where the multiplier, m, represents the slope of the line and the base, b, represents the y-intercept of the line.
Since y = 7x + 2 is written in the form of y = mx + b, it's a linear equation that has a slope equal to 7 and a y-intercept equal to 2.
