Answer:

Using the slope-intercept form, the slope is −35 . The equation of a perpendicular line to y=−3x5+3 y = - 3 x 5 + 3 must have a slope that is the negative reciprocal of the original slope.

Answer:

Step-by-step explanation:

-6x + 3y = -7

to find the x intercept, sub in 0 for y and solve for x

-6x + 3y = -7

-6x + 3(0) = -7

-6x = -7

x = 7/6 <=== ur x intercept is (7/6,0)

to find the y intercept, sub in 0 for x and solve for y

-6x + 3y = -7

-6(0) + 3y = -7

3y = -7

y = -7/3 <=== ur y intercept is (0,-7/3)

Each question has four choices, then the probability to guess a correct answer is $p= \frac{1}{4}$ and the probability to select incorrect choice is $q=1-p=1- \frac{1}{4} = \frac{3}{4}$ .
