Question

HELP!
Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (4,2)

Answer 1

k..with the given data.... the Eqn. of a line = > y -y1 = m(x-x1)

=> y-2 = 2 (x-4)

=> y-2 = 2x - 8

=>-2x+y = -8+2

=> -2x +y = -6

=> 2x-y = 6

or 2x-y-6=0 >>>>ans

Answer 2

Slope- Intercept form is y - y1 = m(x - x1) where m is your slope, so just substitute in what they've given you.

y - 2 = 2(x - 4)
y -2 = 2x - 8
y = 2x - 6

Answer 13

Choose the equation of the line that contains the points (-3,2) and (5,-5)
Answer choices are:
A:y=-7/8x-5/8
B:y=-7/8x+5/8
C:y=-7/8-5/8x

Answer 14

Look :
Things you see before x is slope right ?:)
(In equations :) )

Answer 15

you need to first find the slope using the slope formula :
slope(m) = (y2 - y1) / (x2 - x1)
(-3,2) x1 = -3 and y1 = 2
(5,-5) x2 = 5 and y2 = -5
now lets sub our info into the formula
m = (-5 - 2) / (5 - (-3)
m = -7/8

now we will use this formula : y - y1 = m(x - x1)
m = -7/8
(-3,2) x1 = -3 and y1 = 2
now lets sub
y - 2 = -7/8(x - (-3)
y - 2 = -7/8(x + 3)
y - 2 = -7/8x - 21/8
y = -7/8x - 21/8 + 2
y = -7/8x -21/8 + 16/8
y = -7/8 - 5/8

any questions ?
