Question

PLEASE HELP ME Determine the equation of the line if you have a slope of -2 and a point E (1,1)

A y = -2x + 3

B y = 2x + 3

C. y = -3x + 2

D. y = 3x - 2

Answer 1

A (-2x+3)

Explanation:

The slope-intercept form of a linear equation is y = mx+b. M being the slope and b being the y-intercept. We know the slope is -2, so we have y = -2x+b. If point E is at (1,1), we can use that to get our y-intercept (where x=0). That point would be (0,3) since a negative slope increases the farther left along the x-axis you go and has an absolute value of 2, thereby increasing by 2 for every 1 travelled along the x-axis. (0,3) is the y-intercept thus we get y = -2x+3.

Answer 2

A is the correct answer

Explanation:

The y intercept is at three when you go down 2 and to the right 1

you get the point (1,1)
