First calculate the change in y over the change in x:
by - ay -1 - 1 -2
———— = ——— = —— = 1
bx - ax -2 - 0 -2
The slope is 1:
Second set up the equation in y = mx + b form (m is your slope!) ...
y = (1)x + b
... and plug in either point you have used (A or B)
A(0,1)
1 = (1)(0) + b
1 = b
Now you have your equation: y = 1x + 1
Your final step is to plug in point C to solve for your missing variable:
y = (1)(5) + 1
y = 6
the value of H therefore is 6
Answer: The ACT is a standardized test that measures a student's skills in five core areas: English, math, reading, science, and writing (optional). Students in grades 11 and 12 take the ACT so that they can submit their scores to colleges as part of the college application process. 75 questions in 45 min.
