<span>4x + 8y = 7
8y = -4x + 7
y = -1/2x + 7/8 this equation has slope = -1/2
</span><span>line perpendicular to the line 4x + 8y = 7, so the slope = 2
</span><span>same y -intercept as −3x + 5y = −2
</span><span> y intercept means x = 0
</span> 5y = −2
y = -2/5
so
b = -2/5
answer:
equation:
y = 2x - 2/5

Answer: Choice D</h3>
======================================================
Explanation:
The given equation is in slope intercept form y = mx+b
We see that m = 1/2 is the slope of y = (1/2)x-7
We'll use this slope along with the point (x1,y1) = (-3,-2) to get the following

Which is why choice D is the answer.
Note: this final equation is in point slope form.

Answer:
16/18
8/9
Step-by-step explanation:
the answer is B) -8/9
Let "a" and "b" be the two numbers
So a*b=-8 and a+b=-7
Therefore S=-7 and P=-8
Using (x^2)-S+P=0 => (x^2)-(-7)+(-8)=0 => (x^2)+7-8=0
By factorizing we get (x+8)(x-1)=0
So a can be either -8 or 1 and b can be 1 or -8
Meaning that the two numbers are -8 and 1.
