Which graph represents the solution to the given system? y=4x+4 y=4x-3
2 answers:
Answer:
Refer the attached figure.
Step-by-step explanation:
Given : System of equation
To find : Which graph represents the solution to the given system?
Solution :
Equation plotted with a red line passing through (-1,0) and(0,4).
Equation plotted with a blue line passing through (0,-3) and(0.75,0).
As their slopes are equal i.e. m=4.
So, the equation of lines are parallel.
There is no solution of the equations.
Refer the attached figure of the equations.
Hello Jessica!
Here's a little tip: Cancel out all of the options that do not have a line crossing the y-axis at positive 4 and a line crossing the y-axis at negative 3. That should narrow down the possible answer choices significantly.
Also take two points, and use the formula
to find out the slope. If both of the lines slope are not 4 (hence m = 4 in the equation), then those are not the correct answers.
Using both of these tactics, you can solve the problem without visible graphing calculator.
