Tiffany's goal is to earn a semester average of 90 in her biology class. her teacher uses the following equation to determine semester averages, where a is the semester average, f is the first nine weeks’ grade, s is the second nine weeks’ grade, and e is the final exam score. a=3(f+s)+e/7 Tiffany made an 88 for the first nine weeks and a 91 for the second nine weeks. What is the minimum score she needs on the final exam to have a semester average of 90? 91
95
93
89

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
