Question

Write the equation of the line, given the y and x-intercepts.

y-intercept = –2, x-intercept = –3

(need help asap so please hurry thank you!!)

Answer 1

y = -(2/3)m - 2

Explanation:

recall that the general equation of a straight line in slope-intercept form is

y = mx + b

where, m is the slope and b is the y - intercept

here we are given that the y - intercept is -2, hence the equation becomes:

y = mx + (-2)

or

y = mx -2

we are also given that the x-intercept is -3, which means that when y = 0, x = -3 (simply substitute this into our new equation to solve for m)

0 = m(-3) -2

0 = -3m - 2 (add 3m to both sides)

3m = -2 (divide both sides by 3)

m = -(2/3)

hence our equation is now

y = -(2/3)m - 2
