Answer:
Step-by-step explanation:
y intercept is 3
y - 4 = 3 ( x - 4)
y - 4 = 3x - 12
y < 3x - 8
not equal to because the line is dashed.
not greater than because the shading is below the line
(Credit to guy/girl above) 63 miles 10 1/2 x 6 is 63.
Answer:
25. No slope
Step-by-step explanation:
25. Y2 - Y1 / X2 - X1
= -8 - (-3) / 9 - 9
= -5 / 0
= no slope; straight line
Use this formula (Y2 - Y1 / X2 - X1) for each ques.
Answer:
Step-by-step explanation:
Consider an equation: 
Here, m is the slope of the line and c is the y-intercept.
Given equation is 
Here, slope is 
As product of slopes of two perpendicular lines is equal to 
, slope of the required line is 
.
Let 
Equation of the required line is 
Answer:This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25
