Answer:

2x +3y = 15 or y = -2/3x +5

Explanation:

You want the equation of the line with y-intercept 5 and x-intercept 7.5.

Equation

The intercept form equation can be written ...

x/a +y/b = 1

where 'a' is the x-intercept and 'b' is the y-intercept.

The given intercepts of a=7.5 and b=5 mean we can write the equation as ...

x/7.5 +y/5 = 1

Multiplying by 15 gives the standard-form equation ...

2x +3y = 15

Solving for y gives the slope-intercept equation ...

y = -2/3x +5
