## anonymous one year ago what it the equation of a line that has a slope of 2, a y intercept of 2 and passes through the points 1,1 and 2,0

All you need is the slope and the y-intercept. Use the slope-intercept form of the equation of a line: $$y = mx + b$$ where m = slope, and b = y-intercept.

2. mathstudent55

The line with slope 2 and y-intercept 2 does pass through the point (0, 2), but it does not pass through the point (1, 1). Are you sure you got that point correctly?

sorry the slope is one

4. anonymous

a line which passes through (1,1) and (2,0) has slope $=\frac{ 0-1 }{ 2-1 }=-1$ so check your question again.

5. mathstudent55

If the slope is 1 and the y-intercept is 2, then the equation is $$y = x + 2$$ This line passes through (0, 2), but not through (1, 1).

point is given (2,0) not (0,2)

7. anonymous

i think slope should be -1

8. anonymous

options y=-1/2x-2 y=-x-2 y=-1/2x+2 y=-x+2
