Irina uses data that she collected on how many minutes she and her friends studied for a test (x) and the grade each received on the test (y). she then determined the equation to be y=0.58x+44.7. use this equation to predict approximately what grade a friend of hers would receive after studying for 75 minutes.

b

step-by-step explanation:

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

the answer is -1 for this question
