Write each equation in slope-intercept form, and then find the slope y-intercept

-y=3x

The equation in slope-intercept form of - y = 3x is y = - 3x and slope is - 3 and y-intercept is 0

Solution:

Need to write following equation in slope intercept form.

-y = 3x

And determine the slope intercept form.

Slope intercept form of a line is y = mx + c where m = slope and c is constant.

Lets represent - y = 3x in slope intercept form.

Multiplying both the sides with - 1, we get

-1 x - y = - 1 x (3x)

=> y = - 3x

On comparing it with y = mx + c, we can say than m = - 3 and c = 0.

Hence slope intercept form of - y = 3x is y = - 3x and slope is - 3 and y-intercept is 0
