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:

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

15.36 per mile

but forgot to round

i am pretty sure
