Answer

y=-2x+4

Work Step by Step

You have to put it into slope-intercept form. Use two points (2,0)(1,2) and use the slope formula (m=$\frac{y2-y1}{x2-x1}$): m=$\frac{2-0}{1-2}$=$\frac{2}{-1}$=-2. The slope is -2. Plug it into the slope-intercept form: y=mx+b 0=2(-2)+b b=4 Now, put the values into the equation: y=-2x+4
