i have two questions please 2) Select the equation of a line that is perpendicular to the line on the graph and passes through the point (3, 2). y = 1 over 3 x + 3 y = -1 over 3x + 3 y = 3 x + 2 y = - 1 over 3 x + 2 3) Write the equation of the line that is parallel to the line y = -3x + 12 and passes through the point (-1, 6). y = one thirdx + 7 y = -3x + 3 y = one thirdx + 3 y = -3x + 7
the graph is for the first one really need help.
Desmos graphing will help you with this :D
anyone
You need to find the slope of the line in the graph first. Slope = rise / run. You need to pick two suitable points on the line to find the slope.
My estimate is the line crosses the x-axis at (-2/3, 0) and the y-axis at (0,2) Slope = rise / run = y-intercept / x-intercept = 2 / (-2/3) = - 2 * 3/2 = -3 Slope of the perpendicular line will be the negative reciprocal of the slope. Therefore, slope m = -1/3 y = mx + b y = -1/3x + b It passes through (3,2) put x = 3, y = 2 and solve for b.
like i know it would be over something bc C a stupid answer
so the b would be the 2 right
y = -1/3x + b It passes through (3,2) when x = 3, y = 2 2 = -1/3 * 3 + b 2 = -1 + b b = 3 y = -1/3x + 3
For #3) What is the slope of the line y = -3x + 12 ?
explain a little
y = -3x + 12 Compare it to the general formula y = mx + b where m is the slope. Therefore, slope of the line y = -3x + 12 is ?
it would be y=-3x+7
nvm i got it
