Hey there! :)
Answer:
y = 10/9x + 8/3
Step-by-step explanation:
A line that is perpendicular to y = -9/10x - 10 has a slope that is the negative reciprocal. Therefore:
-9/10 --> 10/9. This is the slope of line q.
Use the formula y = mx + b where:
m = slope
x = x coordinate of point
y = y coordinate of point.
-4 = 10/9(-6) + b
-4 = -60/9 + b
Create a common denominator:
-36/9 = -60/9 + b
24/9 = b
Simplify:
b = 8/3.
Rewrite the equation:
y = 10/9x + 8/3
Answer:
1
Step-by-step explanation:
Mistake in the second step.
We must add positive numbers or negative ones.
Here he had add the positive and negative numbers and that is the mistake
Here 5 is positive because -×-=+
In the second step, we must add the positives that are 3 and 5 and subtract from 7.
Hope it will help you.
