Find the solution for the equation y=4x-3
2 answers:
Answer:
(-4,-19)
Step-by-step explanation:
Substitute the points into the equation and see if it is true
y = 4x-3
-3 = 4(4) -3
-3 = 16-3
-3 = 13 false
-19 = 4(-4) -3
-19 = -16-3
-19 -19 true
Answer:
(-4, -19)
Step-by-step explanation:
To find the solution plug in the coordinates (x,y)
You want a set of coordinates that make it so that both sides are equal
For example:
(-4, -19)
y = 4x - 3
-19 = 4(-4) - 3
-19 = -16 - 3
-19 = -19
Good! Because both sides are equal
The first option gives you 0 = 16 (not true)
Third gives you 2 = 17 (not true)
Last one gives you 0 = -3 (not true)
