Rewrite the following equation in slope-intercept form. 14x + 15y = 11 Write your answer using integers, proper fractions, and i
Goshia [24]
Answer:
y = (-14/15) x + (11/15)

Explanation:
The slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept

The given is:
14x + 15y = 11

To put this in slope-intercept form, we will need to isolate the y as follows:
14x + 15y = 11
15y = -14x + 11
y = (-14/15) x + (11/15)
were:
m is the slope = -14/15
c is the y-intercept = 11/15

Hope this helps :)
