How would you write the equation with a slope of 2/3 and a y-intercept of -3 in slope- intercept form
Alexxandr [17]

y=2/3x-2

Explanation:

The equation of a line can be written as y=mx+c

m=slope and c = y-intercept

The point at the x−intercept has coordinates (-3,0)

In y=mx+c

0=2/3(3)+c

0=2+c

-2=c

The equation is y=2/3x-2
