Slope intercept form

Question

Write each equation in slope intercept form. Find the slope and the t intercept.

Y= 2x-1

y=2/5x+2

2y-8=0

5x-6y=18

7x+2y=4

6y=-6+3x

Answer 1

y=ax+b is the standard form for a linear equation where a is the slope and b the intercept on the y axis of the line. So we can write the values of a and b for each of the listed equations: a=2, b=-1, y=2x-1; a=2/5, b=2, y=2x/5+2; a=0,b=4, y=4; a=5/6,b=-3, y=5x/6-3; a=-7/2,b=2, y=-7x/2+2; a=1/2,b=-1, y=x/2-1.

Answer 2

Y= 2x-1
slope = 2
y-intercept = -1

y=2/5x+2
slope = 2/5
y-intercept = 2

2y-8=0
2y=8
y=0*x+4
slope = 0
y-intercept = 4

5x-6y=18
y=5/6x-3
slope = 5/6
y-intercept = -3

7x+2y=4
y=2-7/2x
slope = -7/2
y-intercept = 2

6y=-6+3x
y=x/2-1
slope = 1/2
y-intercept = -1
