The points (14,22) and (49,77) form a proportional relationship. Find the slope of the line through the points. Then use the slope to graph the line.
The slope is

Step-by-step explanation:

The slope is the change of y over the change of x.

the change of y:77-22=55

the change of x:49-14=35

55/35 simplified is 11/7

Here's a graph of the line segments connected on desmos:

your question does say to graph a line though, so add arrows instead of dots in my screenshots shown

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign
