Studdy Solution

STEP 1

1. Each equation is in or can be converted to the slope-intercept form of a linear equation, which is y=mx+b y = mx + b .
2. In the slope-intercept form, m m represents the slope and b b represents the y-intercept.

STEP 2

1. Identify the slope and y-intercept for each equation already in slope-intercept form.
2. Rearrange equations that are not in slope-intercept form to identify the slope and y-intercept.

STEP 3

For the equation y=3x+4 y = 3x + 4 :
- The equation is already in the form y=mx+b y = mx + b . - The slope m m is 3 3 . - The y-intercept b b is 4 4 .

STEP 4

For the equation y=5x1 y = -5x - 1 :
- The equation is already in the form y=mx+b y = mx + b . - The slope m m is 5 -5 . - The y-intercept b b is 1 -1 .

STEP 5

For the equation y=23x2 y = \frac{2}{3}x - 2 :
- The equation is already in the form y=mx+b y = mx + b . - The slope m m is 23 \frac{2}{3} . - The y-intercept b b is 2 -2 .

STEP 6

For the equation y+7=4x y + 7 = 4x :
- Rearrange to slope-intercept form by subtracting 7 from both sides: $ y = 4x - 7 \] - The slope \( m \) is \( 4 \). - The y-intercept \( b \) is \( -7 \).

STEP 7

For the equation y3=6x y - 3 = -6x :
- Rearrange to slope-intercept form by adding 3 to both sides: $ y = -6x + 3 \] - The slope \( m \) is \( -6 \). - The y-intercept \( b \) is \( 3 \).

STEP 8

For the equation y+9=34x y + 9 = \frac{3}{4}x :
- Rearrange to slope-intercept form by subtracting 9 from both sides: $ y = \frac{3}{4}x - 9 \] - The slope \( m \) is \( \frac{3}{4} \). - The y-intercept \( b \) is \( -9 \).
The slopes and y-intercepts for each equation are:
1. Slope: 3 3 , Y-intercept: 4 4
2. Slope: 5 -5 , Y-intercept: 1 -1
3. Slope: 23 \frac{2}{3} , Y-intercept: 2 -2
4. Slope: 4 4 , Y-intercept: 7 -7
5. Slope: 6 -6 , Y-intercept: 3 3
6. Slope: 34 \frac{3}{4} , Y-intercept: 9 -9
