Question

Write each equation in slope-intercept form of the equation of a line. Underline the slope and circle the y-intercept in each equation.
a) 3x+4y–12=0

b) 2x+y=1

Answer 1

Y=-3/4x+12
Y=-2x+1

Those are the answers

Answer 2

Answer:

Step-by-step explanation:

Slope-intercept form of the equation is y = mx + c

Where m = slope of the line

c = y- intercept

a). 3x + 4y - 12 = 0 [Standard form of the equation of a line]

4y + 3x = 12

4y = 12 - 3x

$y=\frac{1}{4}(-3x+12)$

$y=-\frac{3x}{4}+\frac{12}{4}$

$y=-\frac{3x}{4}+3$

Here slope of the line is $-\frac{3}{4}$ and y-intercept is 3.

b). 2x + y = 1

y = -2x + 1

Slope of the line is -2 and y intercept is 1
