1. segment ra=segment rb, rs||ab given 2. ∠a = ∠b base ∠'s of isosceles triangle = 3. ∠a = ∠2 if lines ||, corresponding ∠'s = 4. ∠b = ∠1 if lines ||, alternate interior ∠'s = 5. ∠1 = ∠2 substitution

The answer is a hope i

We’re gonna need a picture to refer to in order to figure it out. try reposting your question with the picture included.

To find the x-intercept, make  y  equal to zero, and solve for  x. to find the y-intercept, make  x  equal to zero, and solve for  y.explanation: y=4x−2x-intercept0=4x−2add  2  to both sides of the equation.2=4xdivide both sides by  4.24=xsimplify.12=xswitch sides.x=12y-intercepty=4(0)−2y=−2
