Answer:
d.
Step-by-step explanation:
Answer:
the answer is D
Step-by-step explanation:
9x + y = 7
y = 9x + 7
6 = 9(5) + 7
6 = 45 + 7
<u>6</u> = <u>52</u>
52 52
0.1153846 = 1
Given :
P(-9, -4), Q(-7, -1), R(-2, 5), S(-6, -1).
To Find :
The slope of line PQ.
Solution :
We know , slope is given by :
Therefore, the slope of line PQ is 2/3.
Hence, this is the required solution.
To understand problems like these, we must understand how Slope Intercept Form (SIF) works, and how to solve an equation.
<span>A
</span>SIF is "y=mx+b" where "m" is the slope and "b" is the y-intercept.
y='m'x+''b''
y='3'x-''4''
We can see that in this equation, the slope is 3/1 or 3, and the y-intercept is -4.
<u>B
</u>For this one, we must solve for "y," and then proceed with the same thing we did in Part A.
4x-5y=15
-4x -4x
-5y=-4x+15
/-5 /-5
y='4/5'x-"3"
Using the math above, we can see that the slope is 4/5, and the y-intercept is -3.
