Y= (x-6)/2. Plug that for of first equation into;
Answer:
Math is fun dot com. All one word. (With .)
For other straight lines, I’m assuming you are supposed to graph the intersections, just use the two point form to get the rise and run. The rise / run is the slope. Usually called ‘m’ in formula form. Plug each Straight line formula into the Same web page above and it will graph the line for you. Be sure each line is in the [Y = mX+b ]
Format. Y is the up, X is the over, m is the slope. (Change in Y divided by change in X) (like stairs), and ‘b’ is the Y intercept. That means where the line crosses the Y (up) axis.
Step-by-step explanation:
Answer:
yes, it is
Step-by-step explanation:
plug in the point (1, -1) (x,y) into the equation y = 9x - 10
-1 = 9(1)-10
-1 = 9-10
-1=-1
2x + 22 = 4(x + 3)...distribute thru the parenthesis
2x + 22 = 4x + 12...subtract 2x from both sides, subtract 12 from both sides
22 - 12 = 4x - 2x...simplify
10 = 2x...divide both sides by 2
10/2 = x...reduce
5 = x <==
Answer:
The y intercept is 80 and the line of the best fit is -3/5
