Answer:

y=-3x+4

Step-by-step explanation:

1. Use the saying "rise over run" to find the slope. Starting at the highest dot, we can count down 3 and across 1. This means the slope is -3/1 or -3.

2. After finding the slope, we need to find the y-intercept. Locate where the line crosses the y-axis, in this case it is at 4.

3. Finally, plug in these numbers to the slope intercept format: y=mx+b. 'm' is the slope and 'b' is the y-intercept.

What is the length of AB?

Tresset [83]

Answer:

angle B'CA'= angle BCA..... (common angle)

angle B'A'C = angle BAC.....(corresponding angels)

therefore,

ΔCB'A' ~ ΔCBA. ......(by A-A test of similarity)

therefore,

B'A'/ BA. = CA'/ CA....(congruent sides of congruent triangles)

now, B'A' = 5, CA'= 6 , CA = 6 + 3 = 9

5 / BA. = 6 / 9

therefore, 5 / BA. = 2 / 3

$ba \: = \frac{5 \times 3}{2 } \\ = \frac{15}{2} \\ = 7.5$

Answer : AB = 7.5 units
