The form of the linear equation is
![y=mx+b](https://img.qammunity.org/2023/formulas/mathematics/high-school/smsb8cbft03lwblmi49nf2l6jby2ofxzws.png)
m is the slope
b is the y-intercept
The given equation is
![y=-2x+3](https://img.qammunity.org/2023/formulas/mathematics/high-school/8rtcwxdfz0uecpm44ag9dzk1bxozaaklsm.png)
Compare it with the form above to find m and b
Since the coefficient of x is -2, then
m = -2
Since m is the slope of the line, then
The slope of the line is -2
The answer is B
