find the equation of the line using exact numbers

Answer:
y = -2x +5
Step-by-step explanation:
The line crosses the y-axis at y=5, so that is the y-intercept. The next grid point it crosses is 1 unit to the right and down 2, so the slope is -2/1 = -2. In slope-intercept form, the equation is ...
y = -2x +5
