Answer:

y = [tex]\frac{5}{3}x-1[/tex]

Step-by-step explanation:

Let the equation of the line is,

y = mx + b

Here m = slope of the line

b = y-intercept

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph attached,

Since, the given line passes through (0, -1) and (3, 4),

Slope 'm' = [tex]\frac{4+1}{3-0}[/tex]

m = [tex]\frac{5}{3}[/tex]

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = [tex]\frac{5}{3}x-1[/tex]
