Solve the system of equations

(4, -3)

Step-by-step explanation:

First turn them into slope intercept form:

y=3x-15

y= -1x+1

then I used a calculator that graphs them for me

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
