Answer:
Step-by-step explanation:
So for the given information, it would be easiest to use slope-intercept form, which is y=mx + b, where m is the slope and b is the y-intercept.
We can plug in 2/3 for the slope, because we are given that.
y=2/3x + b.
To find the y-intercept, plug in the given point for x and y and solve for b.
-5 = 2/3 · (-3) + b
-5 = -2 + b
b = -3
So now we have the complete equation of the line.
<u>y = 2/3x -3</u>
Now to graphing.
We can put the y-intercept, (0, -3), and the given point, (-3, -5) on a graph.
Answer:
Step-by-step explanation:
Let's solve for b.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2x.
−2bx/−2x=6/−2x
b=−3x
Answer:
b=−3x

Let's solve for x.
−2(bx−5)=16
Step 1: Add -10 to both sides.
−2bx+10+−10=16+−10
−2bx=6
Step 2: Divide both sides by -2b.
−2bx/−2b=6/−2b
x=−3b
Answer:
x=−3b
