To find slope intercept form, the formula is y=mx+b.
To find the slope, which is m, the formula is <span>(y2 - y1) / (x2 - x1)
y2=-26
y1=-20
x2=7
x1=5

(-26--20)/(7-5)
the slope is -3

now, to find the y intercept, solve for b.
y=-3x+b

</span>Step 1: Flip the equation.

<span><span>b−<span>3x</span></span>=y</span>
Step 2: Add 3x to both sides.

<span><span><span>b−<span>3x</span></span>+<span>3x</span></span>=<span>y+<span>3x</span></span></span><span>b=<span><span>3x</span>+<span>y

use your coordinates from the table.
b=3(5)-20
b=-5
so, y=-3x-5</span></span></span>

What is the value of v? 4/5(v−7)=2
Nostrana [21]
4/5(v - 7) = 2...distribute the 4/5 thru the parenthesis
4/5v - 28/5 = 2 ...multiply everything by 5
4v - 28 = 10...add 28 to both sides
4v = 10 + 28
4v = 38
v = 38/4 reduces to 19/2 or 9 1/2 <==
