Answer:
3x +4 = -2x -1
Step-by-step explanation:
The line that goes up to the right has a y-intercept of +4. This is where it crosses the y-axis. It's slope (rise/run) is 3/1 = 3, so its equation in slope-intercept form is ...
y = mx +b . . . . where m is the slope, b is the y-intercept
<u>y = 3x +4</u>
The other line has a negative slope and a y-intercept of -1. The slope of that line is rise/run = -2/1 = -2, so its equation is ...
<u>y = -2x -1</u>
__
The solution point will have the x-coordinate that is the solution of the equation ...
y = y
3x +4 = -2x -1 . . . . . . substituting the above expressions for y.
25 total points. You use the equation and subsitute the variable. 3 three-pointers is 3•3 when you make x three. 5 two-pointers is 2•5 when you make y five. 6 free throws is 1•6 where 6 becomes z. The final equation is (3•3) + (2•5) + (1•6). Then you get 9+10+6 which eqauls 25
