The correct answers to this question are:
Add -3.6 to both sides
and
Subtract 3.6 from both sides.
This is because to solve any equation, we need to get the variable by itself on one side of the equation. The only way to do this in one step in the example above is to eliminate the +3.6 term on the left side of the equation. To do this, our two options are to add -3.6 or to subtract 3.6 (because these are technically the same operation).
Hope this helps!
D) is correct.
Looking at the graph, it goes through the point (2, 200) and is very near the point (3, 300). This means it increases by nearly 100 every month; this tells us how much she saves each month.
Answer:
y=3x+2
Step-by-step explanation:
y is going up by 3 as x goes up by 1 so slope=3/1=3.
We can use this pattern to determine what will happen at x=0 (the y-intercept). 5-3=2 so the y-intercept is 2.
Slope-intercept form is y=mx+b where m is slope and b is y-intercept.
The equation is y=3x+2.
Find their gradients using the change in y coords divided by the change in x coords. once you have the gradients (or slopes), multiply them by eachother - if the product is (-1) then theyre perpdendicular, if not, they are either parallel or intersect at a point
