Answer:
d(t) = 60t
Step-by-step explanation:
When d = 0, t = 0 as well, so the y-intercept in 0. The slope of the line would be 60.
Hope this helps!
First divide the total cost by 21. when you get the answer multiply the cost of 1 apple by 8. bam. answer.
The answer to the question above only takes the equation of y minus the y-value in the ordered pair then an equal sign then the slope which in this case is negative six then the parenthesis then then plus two then parenthesis
y+3=-6(x+2)
1) y=-x+4, the slope is -1
2)y=-x+4, slope is -1
3) yes
4)It's the same line if the slopes and y-intercepts are the same, so the number of corresponding points are infinite.
