Lesson 10: Equations of LinesGrade 10 Applied Math

Learning Goals 0 I will successfully solve various linear equations

0 Knowing where to sub the given values0 Understanding the situation/equation 0 Isolating for the unknown variable

0 I will successfully apply what I’ve learned about solving linear equations to help me solve word problems involving linear relationships0 Identifying the variables 0 Therefore statements

Learning Goals 0 I will successfully calculate the slope of a line using the formula

for slope when given two points that lie along the same line0 Use slope formula (given) 0 Identify and label x and y values of the coordinates0 Subtract THEN divide 0 NO DECIMALS!!!! Keep fractions in lowest terms 0 If you can, state as a whole number

0 I will successfully create an equation of a line when given two points that lie along the same line0 Find the slope (m value) 0 Use the m value, and an x & y from ONE of the coordinates, to sub

into y=mx+b 0 Solve for b 0 Restate equation with m and b value

Learning Goals 0 I will successfully create an equation of a line when

given slope and y-intercept, parallel, and slope and a random point that lies along the line0 Sub in m and b values into y=mx+b 0 Parallel lines have the same slope!!! 0 Sub in m, x and y value, solve for b then restate equation

0 I will successfully convert from standard form of a linear equation to slope y-intercept form0 Isolate for y (y on the left, everything else on the right)0 If y has a coefficient (number out front), isolate for y,

then divide both sides by the coefficient

Learning Goals 0 I will successfully calculate the x- and y-intercepts

when given an equation in standard form0 X-int has y = zero 0 Sub in y=0, solve for x0 State as a coordinate (#, 0) 0 y-int has x = zero 0 Sub in x=0, solve for y0 State as a coordinate (0, #)

0 I will successfully graph a linear relationship when given the x- and y-intercepts0Plot the two points, and connect with straight line
