Question

Graph the line whose
y
-intercept is
2
and whose
x
-intercept is
−1
.

Answer 1

Recall that:
When x=0 --> y-int.
so: (0,2) on the graph
When y=0 --> x-int.
so: (-1,0) on the graph.

Now: you have two points and you can find the slope using the slope formula:
\[m=\frac{ y2-y1 }{ x2-x1 }\]
\[m=\frac{ 2-0 }{ 0+1 }=2\]

Point slope form:
y=mx+b
m=slope
b=y-int.
equation of line:
y=2x+2
