Question

The slope of a line is 1/8. The point (8,9) is on the line. Determine the equation of this line

Answer 1

you need to use the equation y = mx + b

Answer 2

do you know how to use the equation

Answer 3

No, My teacher never taught me it, she just gave me the assignment

Answer 4

oh great, well let me explain, on the equation y=mx+b
y= a point on the line
x= a point on the line
m= slope
b = y-intercept

Answer 5

now you have slope of 1/8, points (8,9) equivalent to (x,y)
all you need to find is the y-int, value of b

Answer 6

so the way you set up the equation as follows:
y = mx + b
9 = 1/8(8) + b can you solve for b

Answer 7

is b 8?

Answer 8

correct

Answer 9

so the way you right the equation as follows
y = 1/8x + 8 (you don't put values on x,y, because that represents all the point that passes through that line

Answer 10

ohh okay thank you

Answer 11
