I just need some help on this one :)

1 = slope , the y-intercept is 1, the equation is y = 1x + 1

Step-by-step explanation:

To find the slope, use delta y over delta x

Two points plotted are (-1,0) (0,1)

(1-0)/(0-(-1))

(1/(0+1))

(1/1) = 1

1 = slope

The y-intercept is the point where the graph crosses the y-axis.

The y-intercept is 1

Equation:

y = mx + b

y = 1x + 1

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
