Answer:
2
Step-by-step explanation:
Equation of line: y=2x + 1
y=mx+b
m = slope of line
m = 2
Extra:
Slope = [tex]\bold{\frac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\bold{\left(x_1,\:y_1\right)=\left(-2,\:-3\right),\:\left(x_2,\:y_2\right)=\left(3,\:7\right)}[/tex]
[tex]\bold{m=\frac{7-\left(-3\right)}{3-\left(-2\right)}}[/tex]
y intercept:
[tex]\bold{y=2x+b}[/tex]
Plugin [tex]\bold{\left(-2,\:-3\right)\mathrm{:\:}\quad \:x=-2,\:y=-3}[/tex]
[tex]\bold{-3=2\left(-2\right)+b}[/tex]
Isolate b: [tex]\bold{-3=2\left(-2\right)+b}[/tex]
b = 1
