Answer:

y=3/4x-2

a=(8/3,0)

b=(0,-2)

m=3/4

Step-by-step explanation:

STEP 1

3x-4y =8 substract 3x from both sides

-4y=-3x+8 divide -4 to everything

y=3/4x-2

STEP 2

substitute 0 for y and solve for a (x-intercept)

which of the following represents the equation of the line with an x- intercept of 6 that passes through the point (4,4)?

luda_lava [24]

Answer:

$y=-2x+12$

Step-by-step explanation:

To write the equation of a line, find the slope between two points. Substitute two points into the slope formula. If the equation has an x-intercept of 6 then the line passes through the point (6,0). Use (6,0) and (4,4) in the formula.

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-0}{4-6} =\frac{4}{-2} =-2$
