They -intercept of ƒ ( x) is indicated by the red dot at ( x =0, y =1). In analytic geometry, using the common convention that the horizontal axis represents a variable x and the vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y -axis of the

Answerby jim_thompson5910 (35256) ( Show Source ): You can put this solution on YOUR website! I'm assuming the system is really. 3x-4y+6z=1. 9x+8y-12z=3. 9x-4y+12z=4. Note: I'm going to be using |A| in place of D, |Ax| in place of Dx, |Ay| in place of Dy and |Az| in place of Dz. Solved by pluggable solver: Using Cramer's Rule to Solve Systems
Put all the y on one side of the equation, all numbers on the other. Explanation 7*y+2*y−2=6*y+1−3 Multiply the parenthesis. 7*y+2*y+2*-2=6*y+6-3 7*y+2*y-4=6*y+6-3 9*y-4=6*y+3 Subtract 6y, and add 4. 9*y-6*y-4+4=6*y-6*y+3+4 9*y-6*y=3+4 3*y=7 Divide with 3. y=7/3
