Points a and b have the coordinates shown below.
estimate the length of ab to the nearest tenth of a unit.
a= (-4,7)
b= (-12, -10)
ab = units

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.

Arhombus is a quadrilateral.

Sry i’m so bad at math! wish i could answer #imdumb
