Answer:

y = \frac{4}{3} x +1

Step-by-step explanation:

1: find the perpendicular gradient - this is the negative reciprocal of the original gradient:

y=\frac{-3}{4}x+ 2 \\y=\frac{4}{3} x+c

2: Substitute in the coordinate to find the value of c:

y=\frac{4}{3}x +c\\5 = \frac{4}{3} (3) + c\\5 = 4+c\\c=1

3: Put it all together:

y=\frac{4}{3}x+1

Explain why y +1 = 1.2(x+2) and y-5= 1.2(x – 3) represent the same line, despite having
andrew11 [14]

Answer:

You can manipulate both equations into y = mx + b format and end up with the same result of y = 1.2x + 1.4

Step-by-step explanation:

y + 1 = 1.2(x + 2)

y = 1.2x + 2.4 - 1

y = 1.2x + 1.4

y - 5 = 1.2(x - 3)

y = 1.2x - 3.6 + 5

y = 1.2x + 1.4

So essentially, they're the same equation but in different forms.

The diagram shown is two intersecting lines. The measure of 5 is 47°.
Bingel [31]

Answer:

a) 37º

b) 143º

c) 2x - 5 = 143

Step-by-step explanation:

a) Angles 5 and 7 are vertical angles and therefore have the same measurements.

b) Angles 5 and 6 form a straight line and are therefore supplementary (add up to 180º). 180 - 37 = 143.

c) We found the measure of angle 6 is 143º in part b. We can set that equal to 2x - 5. Therefore the equation is 2x - 5 = 143.
