The work of a student to solve a set of equations is shown: equation a: y = 4 − 2z equation b: 4y = 2 − 4z step 1: −4(y) = −4(4 − 2z) [equation a is multiplied by −4.] 4y = 2 − 4z [equation b] step 2: −4y = 4 − 2z [equation a in step 1 is simplified.] 4y = 2 − 4z [equation b] step 3: 0 = 6 − 6z [equations in step 2 are added.] step 4: 6z = 6 step 5: z = 1 in which step did the student first make an error? (5 points)

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.

Non-euclidean geometry was discovered when, in seeking cleaner alternatives to the fifth postulate, it was found that the negation could also be true a. true b.false
