Given a straight line pq has a gradient of 3 and passes through a point (4,7)
(1)find the equation of the straight line pq
(2)determine the - x intercept of the straight line pq
me: (

Assign variables to the coordinates of the given points

Let the coordinates of P be (x1;y1) and Q(x2;y2)

x1=−1;y1=−5;x2=5;y2=4

Write down the two-point form of the straight line equation

y−y1x−x1=y2−y1x2−x1

Substitute the values and make y the subject of the equation

y−(−5)x−(−1)y+5x+1y+5y+5y=4−(−5)5−(−1)=96=32(x+1)=32x+32=32x−72

Write the final answer

y=32x−312

Step-by-step explanation:

16 is the absolute value

step-by-step explanation:

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
