9.45x+7.65y=160.65 how do i graph this

One way is to plot points

so we know that when x=0, the line crosses the y axis
and likewise, when y=0, the line crosses the x axis

one easy way is using that concept

so

first, set x=0 and solve for y (divide both sides by 7.65)
y=21
(0,21) is a point, aka the line crosses the y axis 21 units above the origin
to graph, start from the origin (intersection of x and y axis) and go up 21 units on the y axis and put a dot there

then set y=0 and solve for x (divide both sides by 9.45)
x=17
(17,0) is a point, aka the line crosses the x axis 17 units to the right of the origin
to graph, start from the origin (intersection of x and y axis) and go left 17 units on the x axis and put a dot there

now connect those 2 dots to graph your line
