Question

What is the slope-intercept form of a line with slope -7 and y-intercept (0,9)?

Answer 1

Hi Mate!!!

Let the line cuts x axis at ( a , 0)

Slope = 9 / -a = -7.

a = 9 /7 and b = 9

Slope intercept form of a line is

( x / a ) + ( y / b ) = 1

Where a is intercept on xais and b is intercept on y axis

[x / (9/7)] +[y / 9] = 1

7x + 9y = 9
