Question

give the formula of the line trough (0,2), parallel to line y=x+3

Answer 1

parallel lines should have same slope
do you know what is slope in this equation y= x +3 ?

Answer 2

yeah I know that the slope is 1 because x=1

Answer 3

But I was struggling with the rest where I thought i had to fill in the coordinates

Answer 4

well u r right slope is one but x isn't one
x have coefficient that's one
so new equation should have m =1
y = 1x + b
now use that order pair replace x and y by their values then solve for b

Answer 5

y-intercept where line cross y-axis when x =0
so you don't have to solve for b
when x =0 the value of y you have with x suppose to be y-intercept
for example \[\huge\rm (0 , 6)\] here x =0 y =6
bec x=0 so that's why y -intercept is 6
u don't have to solve

Answer 6

so y -intercept of new equation is = ??
