5. Please write the equation of a line in y=mx+b format. Find the SLOPE first then find the Y-INTERCEPT (b) Your answer​
castortr0y [4]

Answer:

y = \frac{5}{3}x-1

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 (x_1,y_1) and (x_2,y_2) is,

m = \frac{y_2-y_1}{x_2-x_1}

From the graph attached,

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

Slope 'm' = \frac{4+1}{3-0}

m = \frac{5}{3}

y - intercept 'b' = -1

Therefore, equation of the line will be,

y = \frac{5}{3}x-1
