2a. y - y1 = m(x - x1)
m = (7-3)/(5 + 1) = 4/6 = 2/3
y1 = 7, x1 = 5
y - 7 = 2/3(x - 5)

2b. Slope intercept form: y = mx + b
y = 2/3(x -5) + 7
y = 2/3x -10/3 + 7
y = 2/3x - 10/3 + 21/3
Y = 2/3x + 11/3

How do you simplify this expression then evaluate it if x=2? 5x - 2 + 3 - x
DIA [1.3K]

You just put all of the like terms together, if it has an X combine it and if it doesn't have an X combine it. You end up with 4x-5

<h2>Answer:</h2>

y=\frac{1}{3}x+4

<h2>Explanation:</h2>

Slope-intercept form:

What the variables mean:

Y=the y axis

m=the slope

x=the x-axis

b=the y intercept (the point on the line that crosses the y-axis)

To Calculate the Slope:

1. Find any 2 points on the line

2. The number of units the second point is above the first is the numerator

3. The number of units the second point is to the right of the first is a denominator

(Please see the picture attached)

y=\frac{1}{3}x+b

To Find the Y-Intercept:

1. Find the point on the line that crosses the y-axis

(Please see the picture attached)

y=\frac{1}{3}x+4

Solve for x. x - 7 = 25
andre [41]

Answer:

x = 32

Step-by-step explanation:

x - 7 = 25

To solve equations, you do the some thing to both sides to isolate x.

After adding 7 to both sides we have:

x = 32
