Write an equation of a line in standard form with a x intercept of - 5 and a y intercept of 15.

If this is a slope question then:

We know that the formula for slope is:

y = mx + b (M being slope, X being the x - intercept and y being the y-intercept)

So if the question asks to write an equation of the line with a x-intercept of - 5 and a y - intercept of 15.

So now you substitute - 5 for the x-intercept, and 15 for the y-intercept:

So now it's

y = 15m + - 5

The m stays since there's no value for m.

So the final answer is: y = 15m + - 5
