the line
y= o.15x+ 0.79 represents an estimate of the avgerage cost of gasoline for each year. The line 0.11x-y= -0.85 estimates the price of gasoline in Jan. of each yr.
a) Do you expect the lines to be intersecting, parallel, or perpendicular? Explain your reasoning.
b) Use the equations of the lines to determine if they are parallel. What did you find?
c) Did your answer to part b confirm your expectation in part a?
help me please

a) To determine whether the lines are intersecting, parallel, or perpendicular, we need to compare their slopes. The slope of a line can be found by looking at the coefficient of the x-variable in the equation.
For the first line, y = 0.15x + 0.79, the coefficient of x is 0.15. Therefore, the slope of this line is 0.15.
For the second line, 0.11x - y = -0.85, we need to rearrange the equation into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
By rearranging the equation, we get y = 0.11x + 0.85.
Hence, the coefficient of x is 0.11, which means the slope of the second line is 0.11.
b) To determine if the lines are parallel, we compare their slopes. If the slopes are equal, the lines are parallel.
The slope of the first line is 0.15, while the slope of the second line is 0.11. Since the slopes are not equal, the lines are not parallel.
c) No, the answer to part b did not confirm our expectation in part a. We expected the lines to either be intersecting, parallel, or perpendicular. However, we found that the lines are neither parallel nor perpendicular. Thus, our expectation was incorrect.
