Write an equation of the line that passes through 7,10 and is perpendicular to the line y=1/2-9

slope of the perpendicular line is -1/½=-2.

Now use slope-intercept form of the line equation:

y-10=-2(x-7)=-2x+14, y=-2x+24.

Step-by-step explanation:

it should be a and d. lmk if i'm wrong xd

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
