the answer is three divide by ten
Answer:
1. Slope = -2 , y-intercept = 1
2. Slope = 5 , y-intercept = -15
3. Slope = 1.5 , y-intercept = -2
4. Slope = -3 , y-intercept = 9
Step-by-step explanation:
1. The slope is -2 because using the formula y₁-y₂÷x₁-x₂ you can use the points given to you to get -2. It doesn't matter which one you pick as y1 or y2, just make sure you keep it consistent with the x numberings. I did 1--3 (which becomes 1+3) and 0-2. Those equal 4/-2 which gives you -2. Use these same steps for all of them, but with ones that don't have the points given, just pick two that are whole numbers and not decimals. For finding the y-intercept, just find the point that is on the y axis line. It is given on number one as (0,1). So, the y-intercept is 1. Hope this helps!

Answer:
b
Step-by-step explanation:
this is the correct answer trust
y = 2x + 4
in standard form is
2x - y = -4
Second equation is
x + 2y = 8
Those aren't parallel.
Answer: exactly one solution
Let's solve,
x +2(2x + 4) = 8
5x + 8 = 8
5x = 0
x = 0
y = 2x + 4 = 4
Solution is (0,4)
