Question

Please help! (will give a medal)
Write a point slope equation for the line that passes through the point (8,1) and is parallel to the line given by y=5.8x-9. Do not use parenthesis on the y side.

Answer 1

Parallel means that the slope is the same. So the new slope will be 5.8. Now, you can plug in the values you have (8 for x and 1 for y) into y = mx + b. and solve for b. you get:
y = mx + b
1 = 5.8(8) + b
1 = 46.4 + b
-45.4 = b

So your equation is:
y = 5.8x-45.4

Answer 2

y-1=5.8(x-8)

Answer 3

is the answer

Answer 4

I don't get how they get that answer.

Answer 5

I wrote it in slope-intercept form. They used point slope form: (y-a) = m(x-b)
m is the slope of the line
(b,a) is a point on the line.

Answer 6

In the equation y=9x+41 the slope is 9 right?

Answer 7

That is perfectly correct.

Answer 8

thanks allot! You're the first person who actually helped me! haha

Answer 9

glad to be of service.
