Answer: y = 3/2x + 1
Step-by-step explanation: For a perpendicular line, take the reciprocal of "m" and reverse the sign.
- 2/3 becomes +3/2
Then substitute the y and x values of the given coordinate into the equation and solve for "b"
y = mx + b
-2 = 3/2(-2) + b
-2 = -3 + b
-2 +3 = b
+1 = b Substitute for b in y = (3/2)x + 1
If you think of the equation as an equation for a line.
y=mx+b

Answer:
D
Step-by-step explanation:
A, B, and C are not linear functions
D would be y=x/2
If you graphed y=x/2, you would get the points (4, 2), (7, 3.5), (8, 4), and (10, 5)
It's more obvious if you notice that y is half of x.
Answer:
y=(9/2)x-15
Step-by-step explanation:
To find x-intercept substitute 0 for y and solve for x
-6x + 3(0) = -7
Simplify
-6x=-<span>7
</span>Divide each side by -6
-6x ÷ -6 = -7 ÷ -6
x = 7/6
X = 7/6 is your x intercept
-------------------------------------
To find y-intercept substitute 0 for x and solve for y
<span>-6(0)+3y=-7
Simplify
</span><span>3y</span>=-<span><span>7
</span></span><span>Divide each side by 3
3y </span>÷ 3 = -7 ÷ 3
<span>y = -7/3
Y = -7/3 is your y-intercept
