Question

I need help with algebra 1 please

Answer 1

Step-by-step explanation:

in such cases you need to identify and mark at least 2 points in the coordinate grid and then draw a line through them.

how to find 2 points ? by simply picking 2 values for x and then use the equation to calculate the corresponding y.

I start in such cases usually with x = 0.

the equation terms is that

y = -1/2×0 + 7 = 7

so, our first point is (0, 7).

that means it is on the y-axis itself (again, x=0) up there at the "7" mark.

for a second point I would pick a value for x that allows me to deal with integer numbers in the equation (that gets rid of the -1/2 fraction).

so, because of the -1/2 nature, I would pick an even number like 4 or 6.

so, let's use 6.

y = -1/2×6 + 7 = -3 + 7 = 4.

our second point is therefore (6, 4).

follow on the x-axis to the right until the "6" mark, and then go up 4 units. there you mark the point.

that is how coordinates work.

and now you take a ruler and you draw a line through both points (not just connect the 2 points, but really extend that line in both directions to the edges of the coordinate grid).
