Since y = 5x-1, we can fill it into 3x + 3y = -3. First, let's look at relating to a simpler equation. Let's say that x + y = 9 and y = 3 + 5. Now, we can fill it in to get that x + (3 + 5) = 9. Now, we know that 3+5 is 8, so x + 8 = 9. Now, x = 1. Likewise, we can do the same. For 3x + 3y = -3, all we need to do is to switch the y in 3x + 3y = -3 with 5x - 1. So it would become 3x + 3(5x - 1) = -3. Now we distribute to get 3x + 15x - 3 = -3. Now add three to both sides to get 3x + 15x = 0. Now simplify to get 18x = 0. Now we know that x = 0. Now fill x into y = 5x - 1. So y = 5(0) - 1. Now we know that y = -1.
To check fill in the answer to 3x + 3y = -3.
3(0) + 3(-1) = -3
0 + (-3) = -3
0 - 3 = -3
-3 = -3
Now that our check is completed we now know that x is 0 and y is -1.
Answer:
Side-Side-Side (SSS)
Step-by-step explanation:
I believe these triangles are congruent by the postulate SSS because both triangles have all three sides equal.
first we can find the slope between the two points by using the slope formula
m=(y₂-y₁)/(x₂-x₁)
m=(3-(-7))/(-3-2)
m=(3+7)/(-3-2)
m=10/-5
m= -2
now that we have the slope, we can set up our equation. slope-intercept form is:
y=mx+b
where m is the slope and b is the y-intercept.
since we have the slope, we can choose one of the points that we are given to plug in for x and y, and then solve for b
-7 = 2(-2) + b
-7 = -4 + b
-3 = b
now that we have all the values we need, we can put it into our slope-intercept formula.
y=mx+b
y=-2x+(-3)
y = -2x -3
