Step-by-step explanation:
The answer is 12. This is the step by step
Answer:
0,8 because it's just the y intercept
Answer:
The slope of line h is -9/7
Step-by-step explanation:
mathematically, for two lines that are perpendicular to each other, the product of their slopes is equal to -1
say we have two lines l1 and l2, the product of their slopes m1 and m2 is -1
Mathematically;
m1 * m2 = -1
now, m1 here is 7/9 , we now proceed to calculate m2
7/9 * m2 = -1
7m2/9 = -1
7m2 = -9
m2 = -9/7
