What is the y - intercept of a line that has a slope of 1/4 and passes through point (8, 3)

Substitute the point coordinates into the point slope formula: y-y_1=m(x-x_1). Substitute the slope 1/4 for m, 3 for y_1, and 8 for x_1.

y-3=1/4(x-8), distribute 1/4 inside the parentheses.

y-3=1/4x-2, add 3 to both sides.

y=1/4x+1; the slope-intercept form of a line is y = mx + b, where b is the y-intercept, so in this line the y-intercept is A. 1.

Flauer [41]

Answer:

1.4.5m/s^2

2.6.25m/s^2

3.15m/s^2

4.0.05m/s^2

Step-by-step explanation:

a=v-u

----

t

27-0

------ = 27/6

6

=4.5m/s^2

u=4.5m/s

v=24.5m/s

t=3.2s

(24.5-4.5)÷3.2

=20/3.2

=6.25m/s^2

v=80m/s

u=50m/s

t=2s

(80-50)÷2

15m/s^2

v=0.80m/s

u=0.50m/s

t=6s

(0.80-0.50)÷6

=0.05m/s^2
