4. a triangle has vertices (-2,-3) (3,5) and (8,-1) .
(a) write a matrix expression to represent reflecting the triangle across the x-axis. evaluate the matrix expression and list the coordinates of the vertices of the transformed figure.
(g) write a matrix expression to represent rotating the triangle 90° clockwise. evaluate the matrix expression and list the coordinates of the vertices of the transformed figure.

Jace wrote a sentence as an equation. 56 is 14 more than a number. 14+ = 56 which statement best describes jace's work? jace is not correct. the phrase more than suggests using the symbol > and jace did not use that symbol. jace is not correct. he was correct to use addition, but the equation should be 56+ p = 14 jace is not correct. the first number in the sentence is 56, so the equation should start with 56. jace is correct. the phrase more than suggests addition, so jace showed that 14 plus a variable equals 56. o

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
