Question

What is the slope and x-intercept of y=2x+1?

Answer 1

slope= 2

x intercept=-0.5 or -1/2

Explanation:

y= mx+b

m is the slope, therefore 2 is the slope of the equation.

X-intercept

substitute 0 to y

0=2x + 1

Subtract 1 from both sides

0-1=2x+1-1

-1=2x

Divide both sides by 2

-1/2=2x/2

x=-1/2 or -0.5

Answer 2

slope: 2

x-intercept = -1/2

Explanation:

The equation is in y = mx + b form. m = slope. The slop is equal to 2.

To find the x-intercept set y equal to 0 and solve for x.

0 = 2x + 1

-1 = 2x

x = -1/2
