Given y = 2x − 2, what effect does changing the equation to y = 2x + 2 have on the y-intercept?
A)
graph becomes steeper

B)
no change to y-intercept

C)
graph moves up 2 units

D)
graph moves up 4 units

The graph moves up 4 units

Step-by-step explanation:

If you add 4 to -2, you'll get +2.

Hope this helped!

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

where's the diagram?
